CC -!- FUNCTION: Catalyzes the hydrolysis of the amide bond of N(2)-acetylated
CC L-amino acids. Cleaves the acetyl group from N-acetyl-L-ornithine to
CC form L-ornithine, an intermediate in L-arginine biosynthesis pathway,
CC and a branchpoint in the synthesis of polyamines. {ECO:0000255|HAMAP-
CC Rule:MF_01108}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + N(2)-acetyl-L-ornithine = acetate + L-ornithine;
CC Xref=Rhea:RHEA:15941, ChEBI:CHEBI:15377, ChEBI:CHEBI:30089,
CC ChEBI:CHEBI:46911, ChEBI:CHEBI:57805; EC=3.5.1.16;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01108};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01108};
CC Name=Co(2+); Xref=ChEBI:CHEBI:48828;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01108};
CC Note=Binds 2 Zn(2+) or Co(2+) ions per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_01108};
CC -!- COFACTOR:
CC Name=glutathione; Xref=ChEBI:CHEBI:57925;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01108};
CC -!- PATHWAY: Amino-acid biosynthesis; L-arginine biosynthesis; L-ornithine
CC from N(2)-acetyl-L-ornithine (linear): step 1/1. {ECO:0000255|HAMAP-
CC Rule:MF_01108}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01108}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01108,
CC ECO:0000305}.
CC -!- SIMILARITY: Belongs to the peptidase M20A family. ArgE subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_01108, ECO:0000305}.
