Trypsin serine protease
WebEnterokinase is a serine protease that recognizes the amino acid sequence -Asp-Asp-Asp-Asp-Lys- -X with a high specificity. The enterokinase activates its natural substrate trypsinogen and releases trypsin by cleavage at the C-terminal end of this sequence. The aspartic acid residues can be substituted by glutamic acid. WebNov 12, 2016 · Name and describe the roles of the residues of the catalytic triad of serine proteases. Try to predict the effects of the following mutations on serine protease activity: Ser195 → Cys (S195C); S195A; H57A; D102A. Page updated 11-12-2016. References. Donald Voet, Judith G.
