== Function ==
[[Subtilisin]] is a serine protease.  A 106 amino acid propeptide is cleaved from the N-terminus of '''pro-subtilisin''' to create the '''mature''' active enzym<ref>PMID:4967581</ref>.  See detalis in [[User:Tommie Hata/Introduction to Protein Engineering-Subtilisin]].


[[Subtilisin]] is a serine protease.  It is widely used commercially in detergents.
*'''Selenosubtilisin''' is a semisynthetic selenoenzyme produced by chemical modification of subtilisin<ref>PMID:8385489</ref>.<br />
A 77 amino acid propeptide is cleaved from the N-terminus of pro-Sub to create the mature active enzyme. The images at the left and at the right correspond to one representative Subtilisin, ''i.e.'' the crystal structure of native mature subtilisin from ''Thermococcus kodakarensis'' ([[2z2x]]).
