Enteropeptidase (EC 3.4.21.9) is the glycoprotein enzyme in the small intestine that triggers the activation of the zymogens in pancreatic juice by converting trypsinogen into trypsin. Because of its physiological significance, there have been many studies on the expression, purification, and characterization of enteropeptidase from different species. The baculovirus expression system has been commonly used in research communities and scientific industries for the production of high levels of recombinant proteins, which require posttranslational modifications for functional activity. In the present study, we isolated bovine enteropeptidase catalytic subunit gene from Bos taurus indicus (GenBank accession no. KC756844), and cloned it in pFast Bac HT "A" baculovirus expression donor vector, under the polyhedrin promoter. Recombinant bovine enteropeptidase was expressed in SF-9 insect cells with high expression levels. Recombinant enteropeptidase was purified using Ni-NTA affinity chromatography. A 6-mg quantity of pure active protein was obtained from 100 mL culture using this approach. Its activity and kinetic parameters were determined by cleavage of its fluorogenic substrate Gly-(Asp) 4-Lys-β-naphthylamide. The recombinant bovine enteropeptidase showed a K m value of 0.75 ± 0.02 mM with K cat 25 ± 1 s.
