What is "metalloexopeptidase"

n. (context biochemistry English) An enzyme that functions as a metalloproteinase exopeptidase.

A metalloexopeptidase is a type of enzyme that acts as a metalloproteinase exopeptidase. These enzymes have a catalytic mechanism involving a metal, often zinc. They function in molecular biology as agents that cut the terminal (or penultimate) peptide bonds ending peptide chains. Analgous to slicing the end off a loaf of bread, the process releases a single amino acid (or dipeptide) for use.
