Streptogrisin B is a serine protease and is produced as a zymogen . Streptogrisin B hydrolyzes proteins into larger aliphatic or aromatic amino acids , similar to chymotrypsin . It has disulfide bridges . Streptogrisin B is secreted by Lysobacter enzymogenes , presumably to break down proteins in the environment as a digestive enzyme .
