STANFORD MOORE September4, 1913-August23, 1982 BY EMIL L. SMITH AND C. H. W. HIRS ST A N F O R D M O O R E, Nobel Laureate in Chemistry in 1972, was born in Chicago, Illinois, when his father, John Howard Moore, was a student at the. University of Chicago Law School ~ }.D., 19171. His father was a graduate of West- minster College in New Wilmington, Pennsylvania, and his mother knee Ruth Fowler) of Stanford University. His par- ents were married in 1907 and hac! met at Stanford. It is alleged that this was the origin of the given name of the son. The education of Stanford Moore began at the age of four at a progressive school in Winnetka, Illinois. When he was six, his father moved to a teaching position in the Law School at the University of Florida; he later accepted a posi- tion with Mercer University in Macon, Georgia, where the boy attendect the local public schools. In 1924 I. H. Moore became professor of law at Vanclerbilt University, where he was to serve on the faculty until his retirement in 1949; he liecl in 1966 at the age of eighty-five. In Nashville, Stanford was a student at Peabody Demon- stration School, which was operated by the George Peabody College for Teachers. He was an outstanding student for the seven years he attencled the school, and he maintained a straight A average. Initially his interests were in English and science, and he was fortunate to encounter a teacher, R. O. 355
356 ~ T ~, . BIOGRAPHICAL MEMOIRS Beauchamp, who arouser! his interest in chemistry. In 1931 he entered the College of Letters and Science of Vanclerbilt university, cons~cter~ng a career in aeronautical engineering or chemistry. Unable to decide between the two fields, he pursued both the liberal arts and the basic subjects of the engineering curriculum during his first two years. In his thirc! year at Vanderbilt, he came under the influence of Ar- thur William Ingersoll, who Stan later creclited as stimulating his enthusiasm for organic chemistry and molecular struc- ture. As a result, Stan changed his major subject to chemistry and graduates! from Vanderbilt in 1935 with the bachelor of arts degree, summa cum laude, anct was a recipient of the Founcler's Mecial as the outstanding student in his class. Sur- prisingly, the Stanford Moore who tended to react a rather reclusive life in later years and generally avoided nonscien- unc social activities was a socialite as an undergraduate. He was active in several clubs, president of his fraternity, ancl, as president of the student council, the organizer of the senior A: L: ~ ~ ~ _ 1 ~ prom. In the autumn of 1935, Stan enterer! the Graduate School of The University of Wisconsin with the support of a fellow- ship from the Wisconsin Alumni Research Foundation. Al- though he chose to major in organic chemistry, he elected to do his thesis research with Professor Karl Paul Link, a mem- ber of the Biochemistry Department at Madison. It was sig- nificant for Stan's later development that Link had spent some time years earlier in Graz, Austria, in the laboratory of Fritz Preg1, one of the pioneers in the clevelopment of microanalytical methods. Link required all of his students to master these microanalytical techniques. In retrospect it is apparent that Stan's background, first in engineering and then in microanalysis, hac! an important effect on his later collaborative work with William H. Stein in the development of important new methods of automated analysis.
STANFORD MOORE 357 Moore's thesis research (ultimately summarized in five pa- pers) included a study of the reaction of o-phenylenediamine with various monosaccharides. The products of this reaction, a series of benzimidazoles, project to be readily isolatec! as stable crystalline solids that lent themselves well to the iden- tification of various monosaccharides. These derivatives con tinue to be so used. With the completion of his doctoral dissertation (1939), it was clear that Stan's future was to be in biochemistry. Two attractive options were available: a four-year fellowship at Harvard Medical School and an invitation to become a re- search assistant in the laboratory of Max Bergmann at the Rockefeller Institute for Medical Research in New York. Bergmann hac! been one of Emil Fischer's outstanding col- laborators, and he hac! continued after the First WorIct War to make a series of notable contributions in protein ant! car- bohyctrate chemistry while at the Kaiser Wilhelm Institut fuer Lederforschung in Dresden. With the rise of the Nazi dicta- torship in the early 1930s, Bergmann accepted an offer to join the staff of the Rockefeller Institute, and moved there in 1934. It was through Link's friendship with Bergmann that the invitation for Stanford to go to Rockefeller was pre- sented. As Stan commented later, "The question of whether it would be wiser to go on to medical school or to enter im- mectiately into chemical research was resolved in favor of the latter." When Stan joined Bergmann's group, he became involved in one of the principal concerns of the laboratory, the struc- tural chemistry of proteins. Of particular interest was the . development of methods for the gravimetric estimation of the amino acid composition of proteins by utilizing selective precipitants. This approach hacI been given new impetus two years earlier when William H. Stein joined the laboratory ant! showocI that aromatic sulfonic acids possess desirable prop /
358 BIOGRAPHICAL MEMOIRS erties in that regard. Whereas earlier workers had concen- tratect on precipitants that formed highly insoluble salts with amino acids (the prototype was flavianic acid, user] by A. Kos- se} and R. E. Gross in 1924 for the isolation of arginine), the research in Bergmann's group emphasized the fact that salts of extremely low solubility were unnecessary, provicl~ec! that the precipitant was selective and that the solubility products of the salts were estimated and corrections were applied for the quantity of amino acid remaining in solution. Bergmann suggested that Stan join forces with Bill Stein to develop the solubility product approach as a routine method for amino acids. There was no way at the time to realize that a scientific collaboration had been initiated that wouIcI last for the remainder of the lifetimes of these two young scientists, certainly one of the longest anct most fruit- fu} collaborations in the history of all science. Bill and Stan concentrated their initial efforts on two sul- fonic acid reagents 5-nitronaphthalene-2-sulfonic acid for glycine anct 2-bromotoluene-5-sulfonic acid for leucine and showed that good results could be obtained with hycirolysates of egg albumin and silk fibroin. But with the work well uncler way, the research tract to be terminated when the country suct~enly founc! itself at war at the end of 1941. With the advent of the war, Bergmann's laboratory un- clertook research for the Office of Scientific Research ant] Development (OSRD). Their specific mission was to investi- gate the physiological actions of vesicant war gases Mustard gas, nitrogen mustards) at the molecular level, with the hope of c:leveloping therapeutic agents that might be helpful in overcoming the effects of these compounds on the human body. The rationale for the work was that adequate defensive measures for preventing the ejects of these toxic com- pounds, as well as the retaliatory capabilities of the United States and its allies, would inhibit the use of chemical warfare
STANFORD MOORE agents. Fortunately, the war. 359 these agents were not used during While Bill Stein remained with Bergmann anal his col- leagues to conduct the research in New York, Stan enlisted in 1942 to serve as a technical aide on the National Defense Research Committee of OSRD to coordinate university and industrial efforts on the biological actions of chemical war- fare agents. His base was in Washington, but he made fre- quent trips to Dumbarton Oaks, where the National Defense Research Committee had its offices. Later (1944), Stan was appointed to the Project Coordination Staff of the Chemical Warfare Service, which was clirectecI by William A. Noyes, Jr. The experiences of the service were summarizer] in a volume published after the war, to which Stan (with W. R. Kirner) contributed an article on the physiological mechanisms of action of chemical warfare agents. When the war endecI, Stan was in Hawaii with the Operational Research Section of the Chemical Warfare Service. Max Bergmann died of cancer in 1944 at age fifty-eight. The war work of the laboratory, however, was continuer! by his associates until the encI of hostilities in 1945. At that time most of them moved elsewhere, and the department that Bergmann hacI organizer! was dissolved. At this juncture Herbert Gasser, then director of the Rockefeller Institute, had the wisdom to offer Bill Stein ant! Stan Moore space in the former Bergmann department, along with the opportu- n~ty-on a trial basis to continue the work on amino acid analysis that they had initiates! before the war. In the interim the collaborative efforts of A. I. P. Martin and R. L. M. Synge ant] their associates in EnglancI procluced novel fractionation techniques, notably partition chromatog- raphy. Bill and Stan were aware of this research, although during the war journals arrived from England rather irreg- ularly. When their collaboration was renewoct in 1945, they .
360 BIOGRAPHICAL MEMOIRS decided to explore the possibilities a~orclect by partition chromatography for determining the amino acid composi- tions of proteins. Their work took place in parallel with that of Lyman C. Craig, whose laboratory was located on the same floor and who had been exploring the potential of counter- current distribution in the fractionation of pepticle antibi- OtiCS. As a starting point, Bill and Stan clecidect to develop a column chromatographic method basecI on work by S. R. Els- den and Synge (1941), who hac! demonstrated that useful separations of amino acids and peptides could be obtained with potato starch as the matrix and various two-phase mix- tures of the lower alcohols, such as n-butanol, with aqueous organic acids as the eluant. To render the procedure quan- titative, a suitable micro method for the determination of amino acids in the column effluent was required. To this anti, Bill and Stan stuctiec] the ninhydrin reaction, known since its discovery in 191 ~ to result in the formation of colorer! procI- ucts from all amino acids. They cliscoverecl that reproclucible yields of the product could be obtained when the reaction was concluctecl in the presence of a reducing agent, initially stannous chIoricle. To monitor the progress of the separations effecteci on the starch columns, the eluate was collected in small fractions of equal volume; these were treater] with ninhydrin under reducing conditions, and the colored products were mea- sured spectrophotometrically. The concentrations of colorer] product in each fraction were plotted against fraction num- ber to obtain a so-called effluent-concentration curve. The area uncler each peak on such curves gave the amount of amino acid in the sample. Initially the fractions were collected manually, but the la- bor involved quickly lect to the design and construction of an instrument in which each drop of effluent from a column was
STANFORD MOORE 361 macle to interrupt a light beam incident on a photocell, thereby incrementing a counter. Drops were collectecI into spectrophotometer tubes. When a precleterminect number of drops tract been collectect, a turntable aclvanced to bring a new tube into line. Although this instrument was not the first fraction collector to be describect, it became the prototype for the commercial instruments that soon appearance thereafter in laboratories around the world. With these developments it became possible to refine the chromatographic procedures themselves. In the methods ul- timately described in 1949, three runs were required to de- termine all the amino acicts in a protein hydrolysate. Bill and Stan clescribec! the application of the method to the deter- mination of the compositions of beta-lactogIobulin and serum albumin. The three runs requires! a total of less than 5 milligrams of protein, with a standard error of less than 5 percent, a remarkable achievement at the time. Recognizing the impact this methodology wouIcl have in biochemistry, Bill anti Stan went to considerable lengths to provide cletailecl descriptions of all the necessary steps for the successful ap- plication of their procedures in other laboratories. Most of this information was circulatecI in the form of preprints, well in advance of publication, to anyone desiring access to it. They were to repeat this service to the biochemical commu- nity many times in subsequent years as improvements in methodology were made. In 1949 Herbert Gasser decided that Moore and Stein had demonstrated the competence as indepenclent investi- gators that he hac! hoper! they wouIct develop. As a result the research budget for their laboratory was increased substan- tially. This permitted the recruitment of postdoctoral asso- ciates and additional technical assistants over the next several years, increasing the scope of the research. Space limitations preclude mention of the numerous students and postcloc
362 BIOGRAPHICAL MEMOIRS toral associates who from this time onward were affiliatecI with the Moore and Stein laboratory. The interested reacler is referred to the bibliography of this memoir for further . ~ . Information. Although the starch column procedures represented a breakthrough of the utmost significance in protein chemistry, there were some limitations. First, there was the slow flow rare of the columns (one complete analysis of a protein hy- drolysate required two weeks). Moreover, a fresh column hacI to be prepared for each run, and the separations were sen- sitive to the presence of salts in the sample. Bill and Stan therefore decided to investigate ion-exchange chromatogra ~. ~r phy on sulfonated polystyrene resins as an alternative. They were encourages] by the success attainer! by S. Miles Partridge in England in the preparative-scale fractionation of amino acids by displacement chromatography on such resins. Effective separations of all the amino acids in a protein hydrolysate in a single run were quickly obtained by elusion with sodium citrate and acetate buffers of increasing pH and concentration at various temperatures, but a great deal of painstaking effort was required to stanciarclize the perform- ance of the columns. The problems were finally overcome when more reproclucible resins became available. The suc- cessfu! development of the ion-exchange methoclology not only allowoct a considerable reduction in the time required for analysis of a protein hydrolysate, but for the first time it permitted reliable analyses of the amino acid content of var- ious physiological fluids: urine, plasma' and protein-free ex- tracts of tissues. These methods also resulted! in the discovery and estimation of new components of these fluids. Concurrently, the potential of ion-exchange chromatog- raphy for the separation of peptizes ant! proteins was clevel- oped. It was soon found that certain stable, basic proteins- notably bovine pancreatic ribonuclease and chymotrypsino
STANFORD MOORE 363 yen, and egg-white lysozyme could be chromatographed effectively on TRC-50, a polymethacrylic acid resin. The elu- tion of these proteins from the exchanger occurred in a pre- dictable way in response to changes in pH and ionic strength. Somewhat later the successful fractionation of histories from calf thymus was achieved. Encouraged by these successes, in 1953 Bill and Stan felt the time had arrived to embark on the structural analysis of a protein. It should be recognized that when the events re- corded here were taking place, little more was known about the fundamental chemical structure of proteins than in Emil Fischer's time. It was only in 194S, when Frederick Sanger and his students began elucidating the primary structures of the polypeptide chains in insulin, that convincing evidence was at hand to demonstrate that proteins have unique amino acid sequences. Sanger's success with the insulin chains (21 and 30 residues) showed that the structure of a polypeptide could be deduced from the sequences of smaller peptides derived from it by selective, partial hydrolysis with weak acid or enzymes. Sanger's work also emphasized the problems of separating the complex mixtures of peptides that resulted from such hydrolysis. It was clear, however, that the deter- mination of the primary structure of longer polypeptide chains would be difficult, if not impossible, by the methods used with the relatively small polypeptide chains of insulin. With this background the choice of a protein became a critical decision for Moore and Stein. They elected to inves- tigate the small enzyme ribonuclease, which they had already studied, arguing that knowledge of its structure would almost certainly aid in understanding its enzymic activity. Their work was performed in parallel with that of Christian B. An- finsen and his colleagues in Bethesda, but the approaches of the two laboratories were different and they functioned on a collaborative rather than competitive basis. Indeed, neither
364 BIOGRAPHICAL MEMOIRS Bill nor Stan relished competition in science, although they recognizes! its value in expediting progress. The investigation of the structure of ribonuclease starter! with a sample of the oxidized protein that was hyclrolyzed selectively with the proteolytic enzyme trypsin. The resulting mixture of pepticles was separated by ion-exchange chro- matography on a column of sulfonate(1 polystyrene resin by procedures similar to those user] earlier for the separation of amino acids. The compositions of these peptides showed that the entire sequence (124 residues of ribonuclease was rep- resented. To establish how these pepticles originated, the ox- i(lizec! enzyme was next hydrolyzed with chymotrypsin, a protease with a selectivity different from that of trypsin, to produce a second set of peptides that were likewise separates] on sulfonated polystyrene. From the known selectivities of trypsin and chymotrypsin, largely elucidated years earlier by Bergmann and his colleagues, the order of the trYntic nen- tides in the polypepticle chain was clecluced. Confirmation was obtainer! from another set of pepticles isolated from a peptic hydrolysate. As this work proceeded, it was evident that progress was limited by the rate at which amino acict analyses couIct be performed. With the manual methods then in use, a single run required almost three days and several hundrec! spectro- photometer readings. Thus, work was initiated in 1956 to clevelop automated amino acid analysis. It was only after ex- tensive refinement of the instrumentation that the method was published in 195X. With the resins then available, the analysis time was shortened to twenty-four hours ant! the sensitivity permitted runs on as little as 0.5 micromole. Sub- sequent clevelopments have resultecI in a reduction for the time of analysis to an average of about an hour and increased sensitivity by two orclers of magnitude. The benefits to our , 1 1 1
STANFORD MOORE 365 knowledge of protein chemistry that became possible with the use of the Moore and Stein analyzer have been incalcu- lable. It is a testimonial to the standards of excellence of Moore and Stein that both the original fraction collector they cle- vised and the automated amino acid analyzer clescribed in 195X remain in perfect working order, the former now in the museum at Caspary Hall, the latter still in the laboratory in which it was assembled at the Rockefeller University. The complete covalent structure of ribonuclease was pub- lishec] in 1963, the first such structure for an enzyme. It was then decider] to investigate the inactivation of ribonuclease by iocloacetate. In a series of investigations in which the prog- ress of the reaction at clifferent pH values was followect by amino acid analysis, they showed that inactivation at pH 5 was the result of carboxymethylation on nitrogen-! of histi- dine-! 19 or nitrogen-3 of histictine-12, but not at both sites of the same ribonuclease molecule. Inactivation at lower pH values was found to be caused by reactions with methionine residues; at higher pH by reaction with lysine-41. In this way they were able to propose that histicTines-12 anct -119 are close to one another in the active site of ribonuclease. This proposal, which proved to be central in further investigations of ribonuclease, was subsequently confirmed in other labo- ratories by x-ray analysis, and it permitted interpretation of kinetic studies and nuclear magnetic resonance work else- where that lee! ultimately to a detailed explanation of the mechanism of action for the enzyme. The work on ribonuclease was recognized by the awarcI- ing of the Nobel Prize in Chemistry for 1972 to Moore and Stein, jointly with Anfinsen. Other honors are listed else- where. As the number of students and postdoctoral associates in
366 BIOGRAPHICAL MEMOIRS the Moore-Stein laboratory expanded, the scope of the work enlarged correspondingly. Here we can only mention some of these investigations. These included the determination of the amino acid sequence of pancreatic deoxyribonuclease; investigation of the reaction of cyanate ion with proteins; structural studies with pepsin; the mechanism of action and structure of streptococcal proteinase; studies of the sequence and the active site of ribonuclease Ti; the isolation of 2',3'- cyclic nucleotide 3'-phosphohydrolase and its inhibitor from brain; studies on ribonuclease inhibitors; and many studies on modifications of pancreatic ribonuclease. In addition there were many investigations by younger associates and col- leagues in their laboratory at the Rockefeller University on which the names of Moore or Stein do not appear. From the foregoing and the appended bibliography, it is evident that the collaboration of Moore and Stein continued at the Rockefeller even after Bill Stein suffered a crippling paralysis in 1969. The biographical memoir on William Stein was the last publication submitted by Stanford Moore, just a month before his own death. In this memoir Moore com- ments, "During the early years of our cooperation, Stein and ~ worked out a system of collaboration which lasted for a lifetime. Stein combined an inventive mind and a deep ded- ication to science with great generosity. Over a period of forty years, we approached problems with somewhat different per- spectives and then focused our thoughts on the common aim. If ~ did not think of something he was likely to, and vice versa, and this process of frequent interchange of ideas ac- celerated progress in research. It also helped in writing pa- pers; ~ never drafted a text that Stein could not improve." We include this quote to indicate that we cannot attempt to judge which of the two was responsible for specific contri- butions to their joint accomplishments and those with their collaborators.
STANFORD MOORE 367 With the exception of the war years (1942-45), Moore was away from the Rockefeller for only a year, beginning in 1950. He spent half the time in Brussels, Belgium, setting up a laboratory devotect to amino acic! analysis, and half the year in Cambridge, Englancl, sharing a laboratory with Frederick Sanger when the work on the amino acid sequence of insulin was proceeding. Stan felt that this year in Europe was im- portant both in his development as a scientist ant! in further- ing his interest and collaboration in international scientific . . . activities. Stan served the community of biochemists well as an ecli- tor, as an officer of the American Society of Biological Chem- ists, ant! as chairman of the Organizing Committee for the International Congress of Biochemistry held in New York in 1964. The Congress was a memorable event in its organiza- tion of scientific presentations and its gracious and efficient hospitality. During this Congress Stan began the custom of inviting eight to ten guests for breakfast and lunch in his suite each clay, so that fellow scientists couIct meet in intimate sur- rounctings with their colleagues. He continucc! this practice for another fifteen years at international congresses and at the annual meetings of the American Society of Biological Chemists. Only his declining health forced a termination of this custom. Stanford Moore was intensively and single-minclecIly cle- votecI to science. He consciously avoicled activities that clid not involve science and scientists. This lifelong bachelor was an early riser, and he was at his desk or in the laboratory throughout the clay and on the weekends. Yet he was a gra- cious and hospitable host to his scientific friends and asso- ciates. Nevertheless, he was a conscientious citizen, and for about a year in the 1960s he served on a grand jury in New York hearing testimony on the activities of organized crime (the famous case of the Cosa Nostra). Typical of Stan, after a
368 BIOGRAPHICAL MEMOIRS day of hearings, he would spend the evenings and the week- ends in the laboratory to keep up with his scientific work. It should be noted that none of the methods and instru- ments designed by Moore and Stein was patented. Personal profit was far from their minds. Indeed, Stan Moore had little interest in personal possessions; his small office and bachelor apartment had the minimally effective furnishings. Stan's obsessive neatness both of person and surroundings was legendary. In the last two years of life, as his health deteriorated, Stan lived with the awareness of progressive nerve and muscle de- generation from amyotrophic lateral sclerosis. He kept this knowledge to himself as long as possible, but characteristi- cally finished his writing obligations, disposed of many of his personal possessions, and left his papers and files in a metic- ulously organized condition. He died in his apartment, a short distance from his beloved laboratory at the Rockefeller University where he had spent so many fruitful and satisfying years. Stan's loyalty to the Rockefeller University and his devo- tion to biochemistry were reflected in his will, in which he bequeathed his estate "to be used as endowment toward the salary or research expenses or both of an investigator in the field of biochemistry." As Stan stated in a letter to President Joshua Lederberg of the University, which was delivered after his death, "I would like (to the best of my modest ability) to help a young scholar have the same opportunity that ~ had." Although Stan had requested that no memorial service be held, his friends and former associates felt that he should be honored. This was done at "A Symposium on Protein Chem- istry in Tribute to Stanford Moore" at the Rockefeller Uni- versity on November 4, 1983, at which former members of the Moore-Stein laboratory presented their latest studies and
