RL   Submitted (MAY-2008) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Reversibly catalyzes the transfer of the carbamoyl group from
CC       carbamoyl phosphate (CP) to the N(epsilon) atom of ornithine (ORN) to
CC       produce L-citrulline. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=carbamoyl phosphate + L-ornithine = L-citrulline + phosphate +
CC         H(+); Xref=Rhea:RHEA:19513, ChEBI:CHEBI:15378, ChEBI:CHEBI:43474,
CC         ChEBI:CHEBI:46911, ChEBI:CHEBI:57743, ChEBI:CHEBI:58228; EC=2.1.3.3;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01109};
CC   -!- PATHWAY: Amino-acid degradation; L-arginine degradation via ADI
CC       pathway; carbamoyl phosphate from L-arginine: step 2/2.
CC       {ECO:0000255|HAMAP-Rule:MF_01109}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01109}.
CC   -!- SIMILARITY: Belongs to the aspartate/ornithine carbamoyltransferase
CC       superfamily. OTCase family. {ECO:0000255|HAMAP-Rule:MF_01109}.
