RT "The occurrence of a catabolic and an anabolic ornithine
RT carbamoyltransferase in Pseudomonas.";
RL Biochim. Biophys. Acta 139:91-97(1967).
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, which is a substrate for argininosuccinate
CC synthetase (ArgG) involved in the final step in arginine biosynthesis.
CC {ECO:0000269|PubMed:4962140}.
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; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01109};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC pH dependence:
CC Optimum pH is between 8.5 and 9. {ECO:0000269|PubMed:4962140};
CC -!- PATHWAY: Amino-acid biosynthesis; L-arginine biosynthesis; L-arginine
CC from L-ornithine and carbamoyl phosphate: step 1/3.
CC {ECO:0000305|PubMed:4962140}.
CC -!- SUBUNIT: Homotrimer. {ECO:0000269|PubMed:4962140}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the aspartate/ornithine carbamoyltransferase
CC superfamily. OTCase family. {ECO:0000305}.
