The previous editions of this book established it firmly as an invaluable starting point and concise reference source for chemists, biochemists, microbiologists and others seeking an overview of enzyme chemistry and a gateway to the surrounding literature. In recent years, remarkable advances have been made in the successful commercial application of enzymes and these have been based to a large extent on greater understanding of the underlying chemistry and its interaction with contiguous disciplines of molecular science. This new edition covers these advances in understanding while retaining the basic structure which has proved so effective in earlier years. The aim remains the same: to provide those graduates with some knowledge of chemistry but a limited knowledge of enzymes, with a one-stop access point to this strategically critical field
