Biotechnol. 36:996-1004(2018). CC -!- FUNCTION: Large subunit of the glutamine-dependent carbamoyl phosphate CC synthetase (CPSase). CPSase catalyzes the formation of carbamoyl CC phosphate from the ammonia moiety of glutamine, carbonate, and CC phosphate donated by ATP, constituting the first step of 2 biosynthetic CC pathways, one leading to arginine and/or urea and the other to CC pyrimidine nucleotides. The large subunit (synthetase) binds the CC substrates ammonia (free or transferred from glutamine from the small CC subunit), hydrogencarbonate and ATP and carries out an ATP-coupled CC ligase reaction, activating hydrogencarbonate by forming carboxy CC phosphate which reacts with ammonia to form carbamoyl phosphate. CC {ECO:0000256|HAMAP-Rule:MF_01210}.

CC -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via de novo pathway; CC (S)-dihydroorotate from bicarbonate: step 1/3. {ECO:0000256|HAMAP- CC Rule:MF_01210}. CC -!- SUBUNIT: Composed of two chains; the small (or glutamine) chain CC promotes the hydrolysis of glutamine to ammonia, which is used by the CC large (or ammonia) chain to synthesize carbamoyl phosphate. Tetramer of CC heterodimers (alpha,beta)4. {ECO:0000256|HAMAP-Rule:MF_01210}. CC -!- DOMAIN: The large subunit is composed of 2 ATP-grasp domains that are CC involved in binding the 2 ATP molecules needed for carbamoyl phosphate CC synthesis. The N-terminal ATP-grasp domain (referred to as the CC carboxyphosphate synthetic component) catalyzes the ATP-dependent CC phosphorylation of hydrogencarbonate to carboxyphosphate and the CC subsequent nucleophilic attack by ammonia to form a carbamate CC intermediate. The C-terminal ATP-grasp domain (referred to as the CC carbamoyl phosphate synthetic component) then catalyzes the CC phosphorylation of carbamate with the second ATP to form the end CC product carbamoyl phosphate. The reactive and unstable enzyme CC intermediates are sequentially channeled from one active site to the CC next through the interior of the protein over a distance of at least 96 CC A. {ECO:0000256|HAMAP-Rule:MF_01210}. CC -!- SIMILARITY: Belongs to the CarB family. {ECO:0000256|ARBA:ARBA00009799, CC ECO:0000256|HAMAP-Rule:MF_01210}. CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01210}. CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ CC whole genome shotgun (WGS) entry which is preliminary data. CC {ECO:0000313|EMBL:HAW50636.1}.
