Subtilisin

Function Subtilisin is a serine protease. A 77 amino acid propeptide is cleaved from the N-terminus of pro-Sub to create the mature active enzym. See detalis in User:Tommie Hata/Introduction to Protein Engineering-Subtilisin. Selenosubtilisin is a semisynthetic selenoenzyme produced by chemical modification of subtilisin. Savinase is a subtilisin produced from a lentil. Relevance Subtilisin is widely used commercially in detergents. Structural highlights The active site of Sub contains the . The and the scissile bond is flanked by Cys-Pro-Met-Val.
