Lactocepin
From Wikipedia, the free encyclopedia
Lactocepin (EC 3.4.21.96, CEP, extracellular lactococcal proteinase, lactococcal cell wall-associated proteinase, lactococcal cell envelope-associated proteinase, lactococcal proteinase, PrtP) is an enzyme.[1][2][3] This enzyme catalyses the following chemical reaction
- Endopeptidase activity with very broad specificity, although some subsite preferences have been noted, e.g. large hydrophobic residues in the P1 and P4 positions, and Pro in the P2 position [1,2]. Best known for its action on caseins, although it has been shown to hydrolyse hemoglobin and oxidized insulin B chain
