The LAP3 protein is a cytosolic metallopeptidase that serves as a catalytic entity responsible for the removal of unsubstituted N-terminal hydrophobic amino acids from a variety of peptides. The peptidase activity of LAP3 depends on the presence of Zn(2+) ions, and its substrate specificity can be modulated by binding to other cofactors. LAP3 Protein, Human (HEK293, His) is the recombinant human-derived LAP3 protein, expressed by HEK293 , with C-His labeled tag.
