DEFINITION

Classification: 435/212

Acting on peptide bond (e.g., thromboplastin, leucine amino-peptidase, etc. (3.4)):

(under subclass 195) Subject matter wherein the enzyme catalyzes the hydrolysis of amide bonds in proteins or peptides.

(1) Note. Exopeptidases (peptidases which hydrolyze single amino acids from the terminus of peptide chains) and enzymes having both exo- and endo-peptidase-activities are examples of enzymes for this subclass.

(2) Note. Where the peptide hydrolase activity is unclear or undisclosed and not ascertainable the activity is presumptively that of an endopeptidase.

227, for enzymes which hydrolyze the amide bond in compounds other than proteins or peptides.
