Thermoactinomyces vulgaris serine proteinase
Class

Acting on peptide bonds (peptidases);
Serine endopeptidases
BRITE hierarchy
Reaction(IUBMB)
Hydrolysis of proteins, including collagen
Comment
A peptidase of family S8 (subtilisin family) from Thermoactinomyces vulgaris containing a single Cys, near the active site His, and inhibited by p-mercuribenzoate. The N-terminal extension of the polypeptide chain relative to subtilisin contributes to Ca2+-binding and the high thermostability. The amino acid composition and properties of the thermostable enzyme from Streptomyces rectus var. proteolyticus (formerly included in EC
3.4.21.14 ) are closely similar [1,2].
