ENZYME entry: EC 3.4.21.96
| Accepted Name |
|---|
| lactocepin.
|
| Alternative Name(s) |
|---|
| extracellular lactococcal proteinase. |
| lactococcal cell envelope-associated proteinase. |
| wall-associated serine proteinase. |
| Reaction catalysed |
|---|
| Endopeptidase activity with very broad specificity, although some subsite preference have been noted, e.g. large hydrophobic residues in the P1 and P4 positions, and Pro in the P2 position. Best known for its action on caseins, although it has been shown to hydrolyze hemoglobin and oxidized insulin B-chain |
| Comment(s) |
|---|
- Responsible for the hydrolysis of casein in milk and the provision of
peptides essential for cell growth.
- Specificity differences between lactocepins from different starter
strains may be partly responsible for imparating different flavor
qualities to cheese.
- Belongs to peptidase family S8.
