Secondary Information |
|---|
| Presence in other biological fluids/tissue/cells | blood, milk |
|---|
| Protein Function | Active form is plasmin; primary physiological
role in blood is to dissolve blood clots; In
bovine milk, plasmin is present mostly as plasminogen,
and the plasmin system is controlled by activators
and inhibitors; |
|---|
| Biochemical Properties | Plasmin catalyzes cleavages of Lys↓Xaa and Arg↓X bonds, with a specificity similar to that of trypsin; much less efficient enzyme than trypsin; esters and amides of arginine and lysine are cleaved with relative rates affected by the inherent susceptibility of the leaving group to hydrolysis; Most inhibitors of trypsin also inhibit plasmin |
|---|
| Significance in milk | associated with casein micelIes
in milk and degrades B-, cr,t- and a,z-caseins to y-caseins, proteose-peptones and
possibly I-casein. |
|---|
| PTMs | N-glycosylated; asparagine residue in position 289 |
