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 -!- CATALYTIC ACTIVITY:
CC Reaction=2 ATP + H2O + hydrogencarbonate + L-glutamine = 2 ADP +

CC Note=Binds 4 Mg(2+) or Mn(2+) ions per subunit. {ECO:0000256|HAMAP-
CC Rule:MF_01210};
CC -!- PATHWAY: Amino-acid biosynthesis; L-arginine biosynthesis; carbamoyl
CC phosphate from bicarbonate: step 1/1. {ECO:0000256|ARBA:ARBA00005077,
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}.
