Secondry Information |
|---|
| Protein Function | cystein cathepsin; involved in a normal cellular
protein degradation and turnover; aminodipeptidase |
|---|
| Biochemical Properties | Cysteine cathepsins are optimally active in a slightly acidic pH and
are mostly unstable at neutral pH; exhibit broad specificity, cleave
substrates preferentially after basic or hydrophobic residues; E-64 is a non-selective inhibitor
of all the cysteine cathepsins, with the exception of cathepsin C,
which is only weakly inhibited |
|---|
| Significance in milk | DPP4 is a key enzyme in intermediary metabolism by regulating important glycemic pathways; expression of DPP4 decreases with the onset of lactation |
|---|
| PTMs | Glycosylated: four glycans |
