DEFINITION

Classification: 435/183

ENZYME (E.G., LIGASES (6.), ETC.); PROENZYMES, COMPOSITIONS THEREOF; PROCESS FOR PREPARING, ACTIVATING, INHIBITING, SEPARATING, OR PURIFYING ENZYMES:

(under the class definition) Enzymes, per se, compositions containing enzymes, processes for synthesizing enzymes, and

preparing enzyme compositions, processes for separating enzymes from a source material, or purifying enzymes or processes under the class definition for treating enzymes.

(1) Note. Enzymes, for the purpose of this class, are defined as proteinaceous materials which cause a chemical change in a starting material without being consumed in the reaction with the remaining amount of enzyme generally, after the reaction, the same as originally present.

(2) Note. Processes wherein a microorganism is propagated and an enzyme recovered therefrom or processes wherein a microorganism is cultivated in the presence of a compound or composition which induces or stimulates enzyme formation are included in this subclass.

(3) Note. The chemical changes catalyzed by an enzyme include oxidation-reduction, transfer of methyl or phosphate groups from one molecule to the next, hydrolysis, nonhydrolytic bond cleavage, isomerization, bond formation in the presence of a nucleotide, etc.

(4) Note. Enzymes conjugates, i.e., enzymes which are labeled with relatively small organic molecules compared to the enzyme, are included in this subclass.

(5) Note. Processes for treating enzymes include but are not limited to processes for inactivating an enzyme, processes for enhancing enzyme activity, processes for forming granular or free-flowing enzyme compositions.

(6) Note. Proenzymes or precursors of enzymes are classified with the related enzyme. (7) Note. The bracketed numerals following the titles in this and the indented subclasses refer to the nomenclature system recommended by the Commission on Bio-chemical Nomenclature on the Nomenclature and Classification of Enzymes. The titles include the enzymes defined by the bracketed numerals but are not limited to the enzymes so classified.
