From Proteopedia

Subtilisin (deepskyblue) complex with streptomycin inhibitor (green) and Ca+2 ions (green) (PDB entry 2sic) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image Contents 1 Function 2 Relevance 3 Structural highlights 4 3D Structures of 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[1]. See detalis in User:Tommie Hata/Introduction to Protein Engineering-Subtilisin. Selenosubtilisin is a semisynthetic selenoenzyme produced by chemical modification of subtilisin[2]. Savinase is a subtilisin produced from a lentil[3]. Relevance Subtilisin is widely used commercially in detergents. Structural highlights The active site of Sub contains the . The and the [4]. 3D Structures of Subtilisin Subtilisin 3D structures
