Enterokinase (EK) is a member of the trypsin family of serine proteases, which cleaves proteins following the Lys at the Asp-Asp-Asp-Asp-Lys recognition sequence. In the stomach, EK converts trypsinogen into trypsin. EK has high specificity and high hydrolytic efficiency, making it a widely used biochemical tool for cleaving recombinant fusion proteins. EK can tolerate a variety of detergents and some denaturing agents. EK’s activity is reduced by > 250 mM NaCl, > 2 M urea, > 20 mM, β-ME, > 0.1% SDS and > 250 mM imidazole.
