Xaa-Pro aminopeptidase 2

Gene

XPNPEP2

Organism
Sus scrofa (Pig)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Is a key enzyme in the metabolism of the vasodilator bradykinin. In addition to bradykinin, AP-P also cleaves substance P and peptides of the pancreatic polypeptide family.

Catalytic activityi

Release of any N-terminal amino acid, including proline, that is linked to proline, even from a dipeptide or tripeptide.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
