This handbook provides comprehensive information on all known glycosyltransferases and their related genes. Nearly 100 chapters, contributed by experts in the field, compile the latest information in a concise format for easy reference. Readers have access to the databases for each glycogene with the accession numbers in each chapter, and maps of biosynthetic pathways of glycoconjugates are also given. The book deals comprehensively with enzymes involved in the biosynthesis of carbohydrate chains of glycoconjugates whose genes have been cloned. Application of gene technology to these enzymes has brought significant progress in glycobiology and glycotechnology in the past decade, making knowledge of the glycogenes that encode glycosyltransferases and related enzymes a shortcut to understanding glycobiology. This handbook is essential for research in functional glycomics, integrating glycobiology and glycotechnology, as it comes of age in the post-genomic era.
