Specificità
DPPIV has a post-proline dipeptidyl aminopeptidase activity that hydrolyzes N-terminal dipeptides from the unsubstituted N-terminus of peptides with the sequence of X-Pro-Z and X-Ala-Z. Where X is a nonspecific residue at the N terminus and Z cannot be proline or hydroxyproline.
Applicazioni
Dipeptidyl peptidase IV from porcine kidney has been used in a study to investigate engraftment of donor cells following hepatocyte transplantation. Dipeptidyl peptidase IV from porcine kidney has also been used in a study to investigate the metabolism of glucagon-like peptide-2.
The enzyme from sigma has been used in the determination of DPP-IV inhibitory activity of peptides in porcine skin gelatin hydrolysates.
Azioni biochim/fisiol
The pH optimum for the protease is 7.8-8.0. Dipeptidyl peptidase does not require activators. It is inhibited by diisopropyl fluorophosphate, phenylmethanesulfonyl fluoride, and diethyl p-nitrophenyl phosphate.
Native DPPIV is a ubiquitous type II transmembrane glycoprotein and a serine protease of the S9 prolyl-oligopeptidase family. In vivo, it is synthesized with a signal peptide, which functions as the membrane anchoring domain. There is an 88% sequence homology between the human and porcine kidney enzymes. Both exist as homodimers with a subunit molecular weight of ~30 kDa. The high mannose 100 kDa DPPIV precursor is processed in the Golgi to yield a 124 kDa heavily N-and O-linked mature glycoprotein. It is then sorted to the apical membrane through the concerted action of both N- and O-linked glycans and its association with lipid microdomains. The porcine enzyme contains 18.3% carbohydrates, which the glycan composition is 0.9% fucose, 3.4% mannose, 5.1% galactose, 8.2% glucosamine, and 0.7% sialic acid. DPPIV is highly expressed on endothelial cells, epithelial cells, and lymphocytes. It is also present in plasma in its soluble form.
