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. HAMAP-Rule MF_00181

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-Rule MF_00181

Release of an N-terminal amino acid, preferentially leucine, but not glutamic or aspartic acids.

Cofactor

Binds 2 manganese ions per subunit By similarity. HAMAP-Rule MF_00181

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_00181.

Sequence similarities

Belongs to the peptidase M17 family.
