Protein
Aminopeptidase N
Gene
pepN, LL0305, L102360
Organism
Lactococcus lactis subsp. lactis (strain IL1403) (Streptococcus lactis)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Aminopeptidase with broad substrate specificity to several peptides. It has more affinity for oligopeptides than for dipeptides. It plays an essential role in the metabolism, it may be involved in nitrogen supply or protein turnover By similarity.

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.

Cofactori

Binds 1 zinc ion per subunit By similarity.
