Enterokinase is a specific protease that cleaves after lysine at its cleavage site Asp-Asp-Asp-Asp-Lys. It will sometimes cleave at other basic residues, depending on the conformation of the protein substrate. This product is a high-purity, high-specific activity enterokinase prepared using a recombinant E.coli. It boasts a broad range of applicability (operating temperature: 4-45°C; pH range: 4.5-9.5) and retains partial activity in the presence of various detergents and denaturants.
