Aminopeptidase N

Gene
N/A
Organism
Helicoverpa armigera (Cotton bollworm) (Heliothis armigera)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Acts as a receptor for B.thuringiensis Cry1Ac delta-endotoxin.1 Publication

Catalytic activityi

Release of an N-terminal amino acid, Xaa-|-Yaa- from a peptide, amide or arylamide. Xaa is preferably Ala, but may be most amino acids including Pro (slow action). When a terminal hydrophobic residue is followed by a prolyl residue, the two may be released as an intact Xaa-Pro dipeptide.1 Publication

Cofactori

Zn2+By similarityNote: Binds 1 zinc ion per subunit.By similarity

Enzyme regulationi

Inhibited by the zinc-chelators 2,2-dipyridyl and 1,10-phenanthroline.1 Publication

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.
