Aspartyl aminopeptidase

Gene

DNPEP

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Aminopeptidase with specificity towards an acidic amino acid at the N-terminus. Likely to play an important role in intracellular protein and peptide metabolism.1 Publication

Catalytic activityi

Release of an N-terminal aspartate or glutamate from a peptide, with a preference for aspartate.1 Publication

Cofactori

Zn2+1 PublicationNote: Binds 2 Zn2+ ions per subunit.1 Publication

Enzyme regulationi

One of the zinc ions is readily exchangeable with other divalent cations such as manganese, which strongly stimulates the enzymatic activity.By similarity

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 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.
