CC -!- FUNCTION: Catalyzes the condensation of carbamoyl phosphate and
CC aspartate to form carbamoyl aspartate and inorganic phosphate, the
CC committed step in the de novo pyrimidine nucleotide biosynthesis
CC pathway. {ECO:0000256|HAMAP-Rule:MF_00001}.
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:0000256|ARBA:ARBA00003822}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=carbamoyl phosphate + L-aspartate = H(+) + N-carbamoyl-L-
CC aspartate + phosphate; Xref=Rhea:RHEA:20013, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:29991, ChEBI:CHEBI:32814, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:58228; EC=2.1.3.2;
CC Evidence={ECO:0000256|ARBA:ARBA00001363, ECO:0000256|HAMAP-
CC Rule:MF_00001};
CC -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via de novo pathway;
CC (S)-dihydroorotate from bicarbonate: step 2/3.
CC {ECO:0000256|ARBA:ARBA00004852, ECO:0000256|HAMAP-Rule:MF_00001}.
CC -!- SUBUNIT: Heterododecamer (2C3:3R2) of six catalytic PyrB chains
CC organized as two trimers (C3), and six regulatory PyrI chains organized
CC as three dimers (R2). {ECO:0000256|HAMAP-Rule:MF_00001}.
CC -!- SIMILARITY: Belongs to the aspartate/ornithine carbamoyltransferase
CC superfamily. ATCase family. {ECO:0000256|ARBA:ARBA00008896,
CC ECO:0000256|HAMAP-Rule:MF_00001}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
