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.
