What is "serratiopeptidase"

n. A proteolytic enzyme (protease) produced by ''Serratia'' enterobacteria.

Serratiopeptidase (Serratia E-15 protease, also known as serralysin, serrapeptase, serratiapeptase, serratia peptidase, serratio peptidase, or serrapeptidase) is a proteolytic enzyme (protease) produced by enterobacterium Serratia sp. E-15. This microorganism was originally isolated in the late 1960s from silkworm Bombyx mori L. (intestine), Serratiopeptidase is present in the silkworm intestine and allows the emerging moth to dissolve its cocoon. Serratiopeptase is produced by purification from culture of Serratia E-15 bacteria.
