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[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].
