Gastricsin.
based on mapping to UniProt P20142
More restricted specificity than pepsin A, but shows preferential cleavage at Tyr-|-Xaa bonds. High activity on hemoglobin.
-!- 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. -!- Belongs to peptidase family A1. -!- Formerly EC 3.4.4.22.
