CC -!- FUNCTION: Presumably involved in the processing and regular turnover of
CC intracellular proteins. Catalyzes the removal of unsubstituted N-
CC terminal amino acids from various peptides. {ECO:0000256|HAMAP-
CC Rule:MF_00181}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Release of an N-terminal amino acid, Xaa-|-Yaa-, in which Xaa
CC is preferably Leu, but may be other amino acids including Pro
CC although not Arg or Lys, and Yaa may be Pro. Amino acid amides and
CC methyl esters are also readily hydrolyzed, but rates on arylamides
CC are exceedingly low.; EC=3.4.11.1;
CC Evidence={ECO:0000256|ARBA:ARBA00000135, ECO:0000256|HAMAP-
CC Rule:MF_00181};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Release of an N-terminal amino acid, preferentially leucine,
CC but not glutamic or aspartic acids.; EC=3.4.11.10;
CC Evidence={ECO:0000256|ARBA:ARBA00000967, ECO:0000256|HAMAP-
CC Rule:MF_00181};
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00181};
CC Note=Binds 2 manganese ions per subunit. {ECO:0000256|HAMAP-
CC Rule:MF_00181};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00181}.
CC -!- SIMILARITY: Belongs to the peptidase M17 family.
CC {ECO:0000256|ARBA:ARBA00009528, ECO:0000256|HAMAP-Rule:MF_00181}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
