The number of translational scientific discoveries and technological innovations derived from the center’s research labs over the course of the past three decades has been remarkable. Equally remarkable have been the number of scientific awards and honors, including Nobel prizes, received by Beckman faculty and the number of young scientists mentored by Beckman faculty who have gone on to prominent positions in academia, bio-technology and related fields. This year we include several featured articles on these accomplishments. In the field of translational medicine, these discoveries range from the causes of skin, bladder and other cancers, to the identification of human stem cells, from the design of new antifungals and antibiotics to the molecular underpinnings of autism, and from opioids for pain -

Thermodynamic and Extrathermodynamic Requirements of Enzyme Catalysis
Biophysical Chemistry 105 (2003) 559–572 Thermodynamic and extrathermodynamic requirements of enzyme catalysis Richard Wolfenden* Department of Biochemistry and Biophysics, University of North Carolina, Chapel Hill, NC 27599-7260, USA Received 24 October 2002; received in revised form 22 January 2003; accepted 22 January 2003 Abstract An enzyme’s affinity for the altered substrate in the transition state (symbolized here as S‡) matches the value of kcatyK m divided by the rate constant for the uncatalyzed reaction in water. The validity of this relationship is not affected by the detailed mechanism by which any particular enzyme may act, or on whether changes in enzyme conformation occur on the path to the transition state. It subsumes potential effects of substrate desolvation, H- bonding and other polar attractions, and the juxtaposition of several substrates in a configuration appropriate for reaction. The startling rate enhancements that some enzymes produce have only recently been recognized. Direct measurements of the binding affinities of stable transition-state analog inhibitors confirm the remarkable power of binding discrimination of enzymes. Several parts of the enzyme and substrate, that contribute to S‡ binding, exhibit extremely large connectivity effects, with effective relative concentrations in excess of 108 M. Exact structures of enzyme complexes with transition-state analogs also indicate a general tendency of enzyme active sites to close around S‡ in such a way as to maximize binding contacts. The role of solvent water in these binding equilibria, for which Walter Kauzmann provided a primer, is only beginning to be appreciated. ᮊ 2003 Elsevier Science B.V. All rights reserved. -

Cecile M. Pickart 1954–2006 On April 5 2006, Cecile Pickart, an outstanding biochemist, died follow- ing a protracted battle with kidney cancer. She was only fifty-one years old. The biomedical research community has lost a superb scientist, valued colleague and dear friend. A memorial celebrating Cecile’s life and scientific contributions is being planned for July 21 this year at the Bloomberg School of Public Health at Johns Hopkins University. Cecile had been a leading investigator in the ubiquitin field from its infancy and she continued to make some of the most seminal discover- ies in the field until her death — a point where the field had matured into an enterprise involving thousands of researchers around the world. Photo courtesy of the Bloomberg School of Public Health, John Hopkins University After graduating summa cum laude in 1976 with a B.S. degree in biology from Furman University in Greenville, South Carolina, Cecile earned These polyubiquitin chains were used for the first structural studies of a Ph.D. in biochemistry from Brandeis University. There, she cut her ubiquitin polymers, allowing Cecile and her colleagues to identify key teeth in enzymology under the tutelage of one of the premier enzymolo- residues on the ubiquitin surface that participate in proteasome binding gists of the day, William Jencks. In 1982, she left to study with another and other ubiquitin functions. She then worked out a method to attach renowned enzymologist, Irwin Rose, at the Fox Chase Cancer Center in these chains to substrate proteins. This beautiful work culminated in a Philadelphia, where she began her studies on ubiquitin. -

Hydrogen Bonding in the Ketosteroid Isomerase Oxyanion Hole
PLoS BIOLOGY Testing Electrostatic Complementarity in Enzyme Catalysis: Hydrogen Bonding in the Ketosteroid Isomerase Oxyanion Hole Daniel A. Kraut1, Paul A. Sigala1, Brandon Pybus2, Corey W. Liu3, Dagmar Ringe2, Gregory A. Petsko2, Daniel Herschlag1* 1 Department of Biochemistry, Stanford University, Stanford, California, United States of America, 2 Department of Biochemistry, Brandeis University, Waltham, Massachusetts, United States of America, 3 Stanford Magnetic Resonance Laboratory, Stanford University, Stanford, California, United States of America A longstanding proposal in enzymology is that enzymes are electrostatically and geometrically complementary to the transition states of the reactions they catalyze and that this complementarity contributes to catalysis. Experimental evaluation of this contribution, however, has been difficult. We have systematically dissected the potential contribution to catalysis from electrostatic complementarity in ketosteroid isomerase. Phenolates, analogs of the transition state and reaction intermediate, bind and accept two hydrogen bonds in an active site oxyanion hole. The binding of substituted phenolates of constant molecular shape but increasing pKa models the charge accumulation in the oxyanion hole during the enzymatic reaction. As charge localization increases, the NMR chemical shifts of protons involved in oxyanion hole hydrogen bonds increase by 0.50–0.76 ppm/pKa unit, suggesting a bond shortening of ;0.02 A˚/pKa unit. Nevertheless, there is little change in binding affinity across a series of substituted phenolates (DDG ¼0.2 kcal/mol/pKa unit). The small effect of increased charge localization on affinity occurs despite the shortening of the hydrogen bonds and a large favorable change in binding enthalpy (DDH ¼2.0 kcal/mol/pKa unit). This shallow dependence of binding affinity suggests that electrostatic complementarity in the oxyanion hole makes at most a modest contribution to catalysis of ;300-fold.
