DESCRIPTION

General description

Enteropeptidase (Enterokinase; EC 3.4.21.9) is an enzyme that converts trypsinogen to trypsin, the activity of which is required for the activation of chymotrypsin and procarboxypeptidases. It has an important role in food digestion and may serve as a marker of differentiated enterocytes and goblet cells.

Suitability

Suitable for the screening of inhibitors of Enteropeptidase/Enterokinase.

Principle

The Enteropeptidase/Enterokinase Inhibitor Screening Kit is a simple assay for screening potential inhibitors of enteropeptidase. Enteropeptidase activity is measured by cleaving a synthetic 7-amino-4-trifluoromethyl-coumarin (AFC)-based substrate to yield AFC, a fluorescent product (λex = 380/ λem = 500 nm), proportional to the enzymatic activity present. The substrate includes the ′DDDDK′ recognition sequence for enteropeptidase.
