FunFam 1: Aminopeptidase

There are 4 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Membrane alanyl aminopeptidase. [EC: 3.4.11.2]
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.
  • Is not activated by heavy metal ions.
  • Belongs to peptidase family M1.
  • Formerly EC 3.4.1.2, EC 3.4.3.5 and EC 3.4.13.6.

Glutamyl aminopeptidase. [EC: 3.4.11.7]
Release of N-terminal glutamate (and to a lesser extent aspartate) from a peptide.
  • Also acts on L-alpha-glutamyl-peptides.
  • Calcium-activated and generally membrane-bound.
  • Belongs to peptidase family M1.
8 P16406 P16406 P50123 Q07075 Q32LQ0 Q52JJ6 Q52JJ6 Q95334
Cytosol alanyl aminopeptidase. [EC: 3.4.11.14]
Release of an N-terminal amino acid, preferentially alanine, from a wide range of peptides, amides and arylamides.
  • A puromycin-sensitive, cobalt-activated zinc-sialoglycoprotein that is generally cytosolic.
  • Multiple forms are widely distributed in mammalian tissues and body fluids.
5 K7CGL0 K7CGL0 P55786 P55786 Q11011
Aminopeptidase Ey. [EC: 3.4.11.20]
Differs from other aminopeptidases in broad specificity for amino acids in the P1 position and the ability to hydrolyze peptides of four or five residues that contain Pro in the P1' position.
  • From the plasma fraction of chicken egg yolk.
  • Belongs to peptidase family M1.
