General annotation (Comments)

Function

Thermolysin-like specificity, but is almost confined on acting on polypeptides of up to 30 amino acids. Biologically important in the destruction of opioid peptides such as Met- and Leu-enkephalins by cleavage of a Gly-Phe bond. Involved in the degradation of atrial natriuretic factor (ANF).

Catalytic activity

Preferential cleavage of polypeptides between hydrophobic residues, particularly with Phe or Tyr at P1'.

Cofactor

Binds 1 zinc ion per subunit.

Enzyme regulation

Inhibited in a dose dependent manner by opiorphin.

Subcellular location

Membrane; Single-pass type II membrane protein.

Involvement in disease

Important cell surface marker in the diagnostic of human acute lymphocytic leukemia.

Sequence similarities

Belongs to the peptidase M13 family.
