Protein attributes

Sequence length	491 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

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 By similarity.
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. HAMAP MF_00181
Cofactor	Binds 2 manganese ions per subunit By similarity.
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the peptidase M17 family.
