KEGG   ENZYME: 3.4.23.3Help
Entry
EC 3.4.23.3                 Enzyme                                 

Name
gastricsin;
pepsin C;
pig parapepsin II;
parapepsin II
Class
Hydrolases;
Acting on peptide bonds (peptidases);
Aspartic endopeptidases
BRITE hierarchy
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).
History
EC 3.4.23.3 created 1965 as EC 3.4.4.22, transferred 1972 to EC 3.4.23.3, modified 1986
