CC -!- FUNCTION: Protease which breaks down milk proteins during the growth of
CC the bacteria on milk.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Endopeptidase activity with very broad specificity, although
CC some subsite preference have been noted, e.g. large hydrophobic
CC residues in the P1 and P4 positions, and Pro in the P2 position. Best
CC known for its action on caseins, although it has been shown to
CC hydrolyze hemoglobin and oxidized insulin B-chain.; EC=3.4.21.96;
CC -!- SUBCELLULAR LOCATION: Secreted, cell wall {ECO:0000255|PROSITE-
CC ProRule:PRU00477}; Peptidoglycan-anchor {ECO:0000255|PROSITE-
CC ProRule:PRU00477}.
CC -!- SIMILARITY: Belongs to the peptidase S8 family. {ECO:0000305}.
