Protein attributes

Sequence length	946 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)

Catalytic activity	Release of an N-terminal amino acid, Xaa-|-Yaa- from a peptide, amide or arylamide. Xaa is preferably Ala, but may be most amino acids including Pro (slow action). When a terminal hydrophobic residue is followed by a prolyl residue, the two may be released as an intact Xaa-Pro dipeptide.
Cofactor	Binds 1 zinc ion per subunit By similarity.
Subcellular location	Cell membrane; Lipid-anchor › GPI-anchor.
Sequence similarities	Belongs to the peptidase M1 family.
