subtilisin

subtilisin
A proteinase formed by Bacillus subtilis and other species, similar to the serine proteinases of other molds and bacteria; it catalyzes the hydrolysis of a few specific peptide bonds in certain proteins, converting chymotrypsinogen to chymotrypsin and ovalbumin to plakalbumin in this manner, and cleaves pancreatic ribonuclease into S-peptide and S-protein. SYN: subtilopeptidase.
