Protein attributes

Sequence length	750 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

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). Ref.6
Catalytic activity	Preferential cleavage of polypeptides between hydrophobic residues, particularly with Phe or Tyr at P1'.
Cofactor	Binds 1 zinc ion per subunit. Ref.11 Ref.12
Enzyme regulation	Inhibited in a dose dependent manner by opiorphin.
Subcellular location	Cell 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.
