Protein

Aminopeptidase N

Gene

pepN

Organism
Streptomyces lividans
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Aminopeptidase with broad substrate specificity to several peptides. Shows strong preference for leucine but cleaves also next to Arg and lysine in peptide-bond-containing substrates.

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.
