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 = H(+) + L-citrulline +
CC phosphate; Xref=Rhea:RHEA:19513, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:46911, ChEBI:CHEBI:57743,
CC ChEBI:CHEBI:58228; EC=2.1.3.3;
CC -!- PATHWAY: Amino-acid biosynthesis; L-arginine biosynthesis; L-arginine
CC from L-ornithine and carbamoyl phosphate: step 1/3.
CC -!- PATHWAY: Amino-acid degradation; L-arginine degradation via ADI
CC pathway; carbamoyl phosphate from L-arginine: step 2/2.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the aspartate/ornithine carbamoyltransferase
CC superfamily. OTCase family. {ECO:0000305}.
