The cell cycle remains an attractive target for the development of small-molecule inhibitors for use as both novel chemotherapeutics and research probes. Given the importance of cytoskeletal dynamics and cyclin-dependent kinases for cell-cycle progression, much interest has focused on the...
The design and use of combinatorial protein libraries has become a fast moving field in molecular biology. Different experimental systems supporting various selection schemes are now available. The latest breakthroughs include evolutionary experiments to improve existing binding surfaces,...
The key role played by counter-ions with enzymes in low-water systems has become better appreciated with, for example, large effects on enantioselectivity. In low-dielectric media, counter-ions will associate strongly with charges in the protein or its substrates. Studies of temperature...
Understanding the architectures of multiprotein complexes is a central problem in biology. Of the many chemical methods available, label transfer and cross-linking are becoming more popular. Recently, label transfer has been applied to very large protein complexes with great success, and new...
Multidomain proteins are common in a variety of cellular processes. Their domains are interconnected through short stretches of amino acid residues referred to as linkers. Recent studies on many systems have provided compelling evidence that linkers are more than simple covalent connectors. They...
A selection of interesting papers that were published in the two months before our press date in major journals most likely to report significant results in chemical biology.
The engineering of microbial biosynthetic pathways is advancing rapidly because of new molecular genetic approaches, sophisticated analysis of metabolic flux and the rapid sequencing of diverse bacterial genomes. The classical methods of mutagenesis/selection, originally applied in the...
Oxynitrilases for the preparation of ( R )- or ( S )-cyanohydrins are now readily available. The research efforts of a number of groups have established these enzymes as catalysts with significant potential for application to asymmetric synthesis. Advances made in molecular cloning and genetics...
The production of enantiopure compounds is of steadily increasing importance to the chemical and biotechnological industries. In principal, the application of directed evolution in combination with newly developed screening methods enables the generation of enzymes with improved...
