CC -!- FUNCTION: Catalyzes the second step of the urea cycle, the condensation
CC of carbamoyl phosphate with L-ornithine to form L-citrulline. The urea
CC cycle ensures the detoxification of ammonia by converting it to urea
CC for excretion. {ECO:0000250|UniProtKB:P00480}.
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 Evidence={ECO:0000250|UniProtKB:P00480};
CC PhysiologicalDirection=right-to-left; Xref=Rhea:RHEA:19515;
CC Evidence={ECO:0000250|UniProtKB:P00480};
CC -!- ACTIVITY REGULATION: Negatively regulated by lysine acetylation.
CC {ECO:0000250|UniProtKB:P00480}.
CC -!- PATHWAY: Nitrogen metabolism; urea cycle; L-citrulline from L-ornithine
CC and carbamoyl phosphate: step 1/1. {ECO:0000250|UniProtKB:P00480}.
CC -!- SUBUNIT: Homotrimer. {ECO:0000250|UniProtKB:P00480}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion matrix
CC {ECO:0000250|UniProtKB:P00480}.
CC -!- PTM: Acetylation at Lys-62 negatively regulates ornithine
CC carbamoyltransferase activity in response to nutrient signals.
CC {ECO:0000250|UniProtKB:P00480}.
CC -!- SIMILARITY: Belongs to the aspartate/ornithine carbamoyltransferase
CC superfamily. OTCase family. {ECO:0000305}.
