Target type: molecularfunction
Catalysis of the hydrolysis of a peptide bond not more than three residues from the N- or C-terminus of a polypeptide chain by a mechanism in which water acts as a nucleophile, one or two metal ions hold the water molecule in place, and charged amino acid side chains are ligands for the metal ions. [GOC:mah, https://www.ebi.ac.uk/merops/about/glossary.shtml]
Metalloexopeptidases are a class of enzymes that catalyze the hydrolysis of peptide bonds at the N-terminus of a polypeptide chain. They are characterized by the presence of a metal ion, typically zinc, in their active site. The metal ion plays a crucial role in the catalytic mechanism, coordinating with water molecules and the peptide substrate to facilitate the cleavage reaction. Metalloexopeptidases are highly specific for the amino acid residues at the N-terminus of the substrate, and they can exhibit varying degrees of selectivity for different amino acid sequences. These enzymes are involved in a wide range of cellular processes, including protein degradation, signal transduction, and immune response. They play important roles in the breakdown of proteins into smaller peptides, which can then be further processed or transported. Metalloexopeptidases are also involved in the regulation of protein function by removing N-terminal amino acids that may interfere with the activity of the protein.'
