title: Classification of enzymes and current status of enzyme nomenclature and units.
abstract: Recommendations for the nomenclature and coding of enzymes as presented by the International Union of Pure and Applied Chemistry and the International Union of Biochemistry are summarized and discussed. Units for reporting catalytic concentration of enzymes are briefly reviewed and abbreviations that have been proposed for enzyme names are also described.
