Protein attributes

Sequence length	520 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Presumably involved in the processing and regular turnover of intracellular proteins. Catalyzes the removal of unsubstituted N-terminal amino acids from various peptides.
Catalytic activity	Release of an N-terminal amino acid, Xaa-|-Yaa-, in which Xaa is preferably Leu, but may be other amino acids including Pro although not Arg or Lys, and Yaa may be Pro. Amino acid amides and methyl esters are also readily hydrolyzed, but rates on arylamides are exceedingly low. Release of N-terminal proline from a peptide.
Cofactor	Binds 2 zinc ions per subunit By similarity.
Subunit structure	Homohexamer Probable.
Subcellular location	Cytoplasm.
Sequence similarities	Belongs to the peptidase M17 family.
