DEFINITION

Classification: 435/219

Proteinase:

(under subclass 212) Subject matter wherein the enzyme catalyzes the hydrolysis of amide bonds within a polypeptide chain, i.e., the amide bonds of nonterminal amino acids.

(1) Note. Endopeptidases are examples of enzymes for this subclass, e.g., ficin, bromelin, etc.

(2) Note. Where the peptide hydrolase activity is unclear (e.g., if it can not be determined whether exopeptidase oendopeptidase activity is involved), enzyme activity within the means of this subclass is presumed.

(3) Note. Exopeptidase and enzymes having both exo- and endo-peptidase activity are to be found in subclass 212.
