Recombinant Enterokinase is a highly specific protease of non-animal origin that recognizes Asp-Asp-Asp-Asp-Lys sequence and hydrolyzes peptides at the C-terminal of Lys. It can transform trypsinogen into trypsin, and it can also cleave the fusion protein with this recognition sequence.

Recombinant Enterokinase is homologous to bovine enterokinase and has the same specificity and activity. However, since this product is of non-animal origin, it is free from animal virus and contaminants of other enzymes, and can replace animal-derived enterokinase in various biotechnology processes. Recombinant Enterokinase can fit wide situations (4-45°C, pH 4.5-9.5), and still has partial activity in the presence of various detergents and denaturants.
