Enzyme Nomenclature 1978 is based upon the recommendations of the Nomenclature Committee of the International Union of Biochemistry on the Nomenclature and Classification of Enzymes.This book deals with the naming of enzymes. The text describes problems encountered in the past when individual scientists named enzymes randomly, resulting in duplication, misnomers, and confusion. Some order followed upon the establishment of the International Commission on Enzymes. This book also explains the classification and nomenclature scheme through general principles that should be followed in dealing with enzymes. The text describes the systematic and trivial names, the key to numbering of enzymes, and the rules of classification and nomenclature. The book also contains the enzyme list including the class of oxidoreductases, transferases, hydrolases, lyases, and ligases (synthetases). The appendix contains the nomenclature of electron-transfer proteins, which include flavoproteins, proteins containing reducible disulfide, cytochromes, iron-sulfur proteins, and other metalloproteins. An index lists all the enzymes in alphabetical order. This handy reference will be useful for scientists involved in bio-chemistry, molecular biology, micro-biology, and researchers whose works involve enzyme and medical research.
