DE   lactocepin.
AN   extracellular lactococcal proteinase.
AN   lactococcal cell envelope-associated proteinase.
AN   wall-associated serine proteinase.
CA   Endopeptidase activity with very broad specificity, although some subsite
CA   preference have been noted, e.g. large hydrophobic residues in the P1 and
CA   P4 positions, and Pro in the P2 position. Best known for its action on
CA   caseins, although it has been shown to hydrolyze hemoglobin and oxidized
CA   insulin B-chain.
CC   -!- Responsible for the hydrolysis of casein in milk and the provision of
CC       peptides essential for cell growth.
CC   -!- Specificity differences between lactocepins from different starter
CC       strains may be partly responsible for imparating different flavor
CC       qualities to cheese.
CC   -!- Belongs to peptidase family S8.
