CC -!- FUNCTION: Small subunit of the arginine-specific carbamoyl phosphate
CC synthase (CPSase). CPSase catalyzes the formation of carbamoyl
CC phosphate from the ammonia moiety of glutamine, carbonate, and
CC phosphate donated by ATP, the first step of the arginine biosynthetic
CC pathway. The small subunit (glutamine amidotransferase) binds and
CC cleaves glutamine to supply the large subunit with the substrate
CC ammonia. {ECO:0000256|ARBA:ARBA00043861}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 ATP + H2O + hydrogencarbonate + L-glutamine = 2 ADP +
CC carbamoyl phosphate + 2 H(+) + L-glutamate + phosphate;

CC Evidence={ECO:0000256|ARBA:ARBA00001777};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + L-glutamine = L-glutamate + NH4(+);

CC ChEBI:CHEBI:29985, ChEBI:CHEBI:58359;
CC Evidence={ECO:0000256|ARBA:ARBA00043737};
CC -!- PATHWAY: Amino-acid biosynthesis; L-arginine biosynthesis; carbamoyl
CC phosphate from bicarbonate: step 1/1. {ECO:0000256|ARBA:ARBA00005077}.
CC -!- SUBUNIT: Heterodimer composed of 2 chains; the small (or glutamine)
CC chain promotes the hydrolysis of glutamine to ammonia, which is used by
CC the large (or ammonia) chain to synthesize carbamoyl phosphate.
CC {ECO:0000256|ARBA:ARBA00044031}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion matrix
CC {ECO:0000256|ARBA:ARBA00004305}.
CC -!- SIMILARITY: Belongs to the CarA family.
CC {ECO:0000256|ARBA:ARBA00007800}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
