INTRODUCTION
Progastricsin-C (PGC) is an aspartic proteinase which is synthesized in the gastric mucosa as inactive precursors. PGC is a part of the peptidase family A1 and contains a prosegment which is responsible for stabilizing the inactive form and preventing the entrance of the substrate to the active site. PGC is used as a biomarker for various gastric diseases including Helicobacter pylori related gastritis. PGC is also hydrolyzes various proteins.
DESCRIPTION
PGC produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 380 amino acids (17-388 a.a.) and having a molecular mass of 41.6kDa (Molecular size on SDS-PAGE will appear at approximately 40-57kDa). PGC is expressed with an 8 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
