Descriptor pepsina A
Entry term(s) pepsina
Scope note: Enzima formada a partir del pepsinógeno de cerdo por escisión de un enlace peptídico. Está formada por una cadena polipeptídica única y es inhibida por el metil 2 diaazoacetamidohexanoato. Escinde péptidos preferentemente en los enlaces carbonilo de la fenilanina o la leucina y es la principal enzima digestiva del jugo gástrico.

Scope note: Formed from pig pepsinogen by cleavage of one peptide bond. The enzyme is a single polypeptide chain and is inhibited by methyl 2-diaazoacetamidohexanoate. It cleaves peptides preferentially at the carbonyl linkages of phenylalanine or leucine and acts as the principal digestive enzyme of gastric juice.
