The far reaches of enzymology - pp516 - 520

Jesse G Zalatan & Daniel Herschlag

doi:10.1038/nchembio0809-516

The scope of enzymology has expanded rapidly over the last century, from an early focus on the chemical and catalytic mechanisms of individual enzymes to more recent efforts to understand enzyme action in the context of dynamic, functional biological systems consisting of many interacting enzymes and proteins. Continuing progress in probing the link between molecular structure and function now promises to pave the way for a deeper understanding of the evolution and behavior of the complex biological systems that govern cellular behavior.

Missing in action: enzyme functional annotations in biological databases - pp521 - 525

Nicholas Furnham, John S Garavelli, Rolf Apweiler & Janet M Thornton

doi:10.1038/nchembio0809-521

Annotations of enzyme function provide critical starting points for generating and testing biological hypotheses, but the quality of functional annotations is hindered by uncertain assignments for uncharacterized sequences and by the relative sparseness of validated experimental data. Given the relentless increase in genomic data, new thinking and validation methods are urgently needed to provide high confidence in enzyme functional assignments.

Finding better protein engineering strategies - pp526 - 529

Romas J Kazlauskas & Uwe T Bornscheuer

doi:10.1038/nchembio0809-526

Protein improvement strategies today involve widely varying combinations of rational design with random mutagenesis and screening. To make further progress—defined as making subsequent protein engineering problems easier to solve—protein engineers must critically compare these strategies and eliminate less effective ones.

Vitamins and cofactors: highlights of ESBOC 2009 - pp530 - 533

Edward McDonald

doi:10.1038/nchembio0809-530

The 2009 ESBOC meeting covered advances in synthesis, biosynthesis and biological mechanisms of vitamins and cofactors. Recent exciting developments in the field include the development of 'green' chemistry for manufacture of vitamins, the discovery that some vitamins act directly to regulate gene expression via riboswitches, and initial attempts to exploit the potential of vitamin analogs as therapeutic drugs.
