STAPHOPAIN

Staphopain ( EC 3.4.22.48, staphylopain) is an enzyme.^[1]^[2]^[3] This enzyme catalyses the following chemical reaction

Broad endopeptidase action on proteins including elastin, but rather limited hydrolysis of small-molecule substrates.

This enzyme is present in several species of Staphylococcus.
