pig parapepsin II;
parapepsin II

Class

Hydrolases;
Acting on peptide bonds (peptidases);
Aspartic endopeptidases

Reaction(IUBMB)

More restricted specificity than pepsin A, but shows preferential cleavage at Tyr! bonds. High activity on hemoglobin

Comment

Formed from progastricsin, apparently in the gastric juice of most vertebrates. In addition to the fundus, progastricsin is also secreted in antrum and proximal duodenum. Seminal plasma contains a zymogen that is immunologically identical with progastricsin [6]. In peptidase family A1 (pepsin A family).
