Abstract

A revolution in structural analysis is in progress in the biological sciences that parallels a similar revolution that took place in chemistry 40–50 years ago. This has major implications for chemistry, offering exciting opportunities at the interface between chemistry and biology. The advances are driven by the value of structural information in biology, for understanding biological function, and for applications in structure-based drug design and structural genomics. Two directions are apparent: towards technically challenging biological structures and assemblies, typified by the potassium channel and the ribosome; and towards high-throughput structure determination of many, smaller, proteins, as in structural genomics. In this review, the advances in molecular biology and in structure determination by X-ray crystallography that make these developments possible are discussed, together with appropriate examples.
