CC -!- FUNCTION: Small 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 small subunit (glutamine amidotransferase)
CC binds and cleaves glutamine to supply the large subunit with the
CC substrate ammonia. {ECO:0000256|HAMAP-Rule:MF_01209}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 ATP + H2O + hydrogencarbonate + L-glutamine = 2 ADP +
CC carbamoyl phosphate + 2 H(+) + L-glutamate + phosphate;

CC ChEBI:CHEBI:456216; EC=6.3.5.5; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_01209};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + L-glutamine = L-glutamate + NH4(+);
CC Xref=Rhea:RHEA:15889, ChEBI:CHEBI:15377, ChEBI:CHEBI:28938,
CC ChEBI:CHEBI:29985, ChEBI:CHEBI:58359; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_01209};
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_01209}.
CC -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via de novo pathway;
CC (S)-dihydroorotate from bicarbonate: step 1/3. {ECO:0000256|HAMAP-
CC Rule:MF_01209}.
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_01209}.
CC -!- SIMILARITY: Belongs to the CarA family. {ECO:0000256|ARBA:ARBA00007800,
CC ECO:0000256|HAMAP-Rule:MF_01209}.
