DEFINITION

Classification: 424/94.1

ENZYME OR COENZYME CONTAINING:

(under the class definition) Subject matter s which contain an enzyme or coenzyme.

(1) Note. The bracketed numerals following the titles in the indented subclasses refer to the nomenclature system recommended by the Commission of Biochemical Nomenclature on the Nomenclature and Classification of enzymes. The titles include the enzymes defined by the bracketed numerals.

(2) Note. Included in this subclass are enzyme adducts wherein the enzyme is intended to be subsequently released as the free enzyme.

(3) Note. Enzymes described in terms of the micro-organism producing them should be placed in this and the intended subclass by disclosed enzymic activity. Such patents should be cross-referenced to Class 435 subclasses 183+. Enzyme fragments and Proenzymes should be classified with the holoenzyme.

(4) Note. CAS registry numbers. For individual enzymes see the Index Guide entries for the name or the E.C. number.

For enzyme subclassifications see: Hydrolase = (9027-41-2);

Isomerase = (9013-19-8); Ligase = (9080-13-1); Lyase = (9055-04-3); Oxidoreductase = (9055-15-6); Transferase = (9047-61-4)

For specific enzymes see inverted headings in the Index Guide under such classes as: Aminotransferase = (9031-66-7); Decarboxylase = (9027-22-9); Dehydratase = (9044-86-4); Dehydrogenase = (9035-82-9); Isomerase = (9031-19-8); Kinase (phosphorylating) = (9031-44-1); Oxidase = (9035-73-8); Phosphatase = (9013-05-2); Reductase = (9037-80-3); Synthesaze = (9031-56-5); (5) Note. National Library of Medicine Mesh subject headings. See the printed copy of section D8 for individual coenzymes and enzymes.

Coenzymes = D8.176; Hydrolase = D8.586.277; Esterase = D8.586.277.352; Peptide Hydrolases = D8.586.277.656; Isomerase = D8.586.399; Ligase = D8.586.464; Lyase = D8.586.520; Oxidoreductase = D8.586.682; Transferase = D8.586.913; Multienzyme Complexes = D8.586.277.656

(6) Note. This subclass provides for compositions which contain coenzymes.

(7) Note. A coenzyme is a nonprotein substance whose presence is required for an enzyme to exhibit its catylitic activity and which undergoes a chemical change during the catalytic cycle of the enzyme involved. Regeneration of the original form of the coenzyme requires its participation in a separate reaction.

(8) Note. Since coenzymes are no more than chemical compounds a search in the appropriate chemical class providing for the compound is recommended.
