Structural biologists

More recently, a group in England led by a structural biologist compiled a list of marketed medicines that came from SBDD [133]. These are labeled SBDD in Table 1.2. It can be seen that there is only a little overlap between the two compilations (CADD and SBDD). It can also be seen that the number of pharmaceuticals from SBDD is very impressive. Computer-based technologies are clearly making a difference in helping bring new medicines to patients. 

The term "structural genomics" is used to describe how the primary sequence of amino acids in a protein relates to the function of that protein. Currently, the core of structural genomics is protein structure determination, primarily by X-ray crystallography, and the design of computer programs to predict protein fold structures for new proteins based on their amino acid sequences and structural principles derived from those proteins whose 3-dimensional structures have been determined. Plant natural product pathways are a unique source of information for the structural biologist in view of the almost endless catalytic diversity encountered in the various pathway enzymes, but based on a finite number of reaction types. Plants are combinatorial chemists par excellence, and understanding the principles that relate enzyme structure to function will open up unlimited possibilities for the... 

One of the tasks of structural biologists studying muscle contraction is to determine the organization and shapes of the myosin head in muscle under different physiological conditions. The technique of low-angle X-ray diffraction has unique advantages in this process, particularly since it can be applied to living muscle, which can be stimulated to produce active force or can be studied under a variety of different steady-state conditions. The main problem with X-ray fiber diffraction, as detailed in Squire and... 

For N, the chemists preferred reference, MeN 2, differs from that chosen by structural biologists, NH3. Some manufacturers (e.g. Bruker) use the stractural biologists reference as the default. Shifts on the lUPAC scale are approximately 380.5ppm less positive than on the NH3 scale, for example, on the lUPAC scale, 5( NH3) = -380.4ppm. The exact correction required depends on the resonance frequency of the sample. 

Our assumption here is that the conception of the C.C. and their actual form will one day be as commonplace to structural biologists as Maxwell s equations are now to physicists. The C.C. are out there in nature, just as much as Maxwell s equations. What can be said of them today ...

The discovery of appropriate starting points for the development of potent and specific inhibitors is stiU a challenge. In addition to the usual problems of low abundance and purity that enzymologists and structural biologists are generally faced wifh, lipases present a unique additional difficulty. Unlike other hydrolytic enzymes, e.g. esterases or proteases, the substrates hydrolyzed by lipases are insoluble in water and therefore must be efficiently presented to the enzyme in a separate lipidic phase. The presence of a suitable second phase apparently leads to increased lipase activity and may effect subtle but critical changes to the enzyme s three-dimensional structure. 

This volume completes our two-part miniseries on the Mechanisms of Catalysis. Paul Boyer and I felt that these two volumes would provide a useful summary of the maturity and complexity of enzymology in this last decade of the twentieth century. They will be of interest to biochemists, structural biologists, organic chemists, and perhaps even a molecular biologist or two. 

By comparison with other aspects of rihoflavin biosynthesis, the reduction and deamination steps obtained less extensive coverage in the literature. Recently, however, the topic has been addressed more actively by structural biologists.
