Abstract
Pepsins are the major digestive enzymes of the alimentary canal and operate optimally at the low pH of the stomach. Pepsin A (EC.3.4.23.1), the major component of gastric juice in pigs, is produced by the mucosal cells of the fundus region of the stomach as an inactive precursor, pepsinogen. On secretion into the acidic lumen of the stomach, cleavage of the propart peptide occurs yielding active pepsin as a single chain molecule.
