Enzyme Nomenclature (1978) is an attempt to address the problems and difficulties that arise in the naming of enzymes and coenzymes. In this regard, the International Union of Biochemistry established the International Commission on Enzymes with the task of creating a standard or code for the future naming of enzymes and to correct and organize the existing names and groups. The text is

Nomenclature. Generally, “the Enzyme-catalyzed reactions each have a uniquely assigned classification number. Isomerase-catalyzed reactions have their own EC category: EC 5. Isomerases are further classified into six subclasses: Racemases, epimerases. This category (EC 5.1) includes and epimerases). These isomerases invert stereochemistry at the target chiral carbon. Racemases act …
Enzyme Technology Enzyme nomenclature. All enzymes contain a protein backbone. In some enzymes this is the only component in the structure. However there are additional non-protein moieties usually present which may or may not participate in the catalytic activity of the enzyme.
reasons for opposing the Application include the view that the organic classification of other companies will be at risk, and that stronger labelling is required if the enzyme is approved. Responses to the issues are provided in the Report.

Nomenclature and Classification of Enzymes Naming the Enzymes Enzymes are generally named according to the substrate they complex with or the type of reaction they catalyze.

IUBMB on the nomenclature and classification of enzyme-catalyzed reactions is complex and archaic, with rules that almost always have an exception.

The system categorizes an enzyme into one of six main …
