General annotation (Comments)

Function

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 activity

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.

Cofactor

Binds 1 zinc ion per subunit By similarity.

Subunit structure

Monomer By similarity.

Subcellular location

Cytoplasm By similarity. Note: It may be secreted through an unknown mechanism By similarity.

Sequence similarities

Belongs to the peptidase M1 family.
