Biology:Pepsin B

Pepsin B (EC 3.4.23.2, parapepsin I, pig gelatinase) is an enzyme.^[1] This enzyme catalyses the following chemical reaction

Degradation of gelatin, with manor activity on hemoglobin. Specificity for B chain of insulin is more restricted than that of pepsin A

This enzyme is formed from pig pepsinogen B.
