CC   -!- FUNCTION: Part of the phosphoribosylformylglycinamidine synthase
CC       complex involved in the purines biosynthetic pathway. Catalyzes
CC       the ATP-dependent conversion of formylglycinamide ribonucleotide
CC       (FGAR) and glutamine to yield formylglycinamidine ribonucleotide
CC       (FGAM) and glutamate. The FGAM synthase complex is composed of
CC       three subunits. PurQ produces an ammonia molecule by converting
CC       glutamine to glutamate. PurL transfers the ammonia molecule to
CC       FGAR to form FGAM in an ATP-dependent manner. PurS interacts with
CC       PurQ and PurL and is thought to assist in the transfer of the
CC       ammonia molecule from PurQ to PurL. {ECO:0000256|HAMAP-
CC       Rule:MF_01926}.
CC   -!- CATALYTIC ACTIVITY: ATP + N(2)-formyl-N(1)-(5-phospho-D-
CC       ribosyl)glycinamide + L-glutamine + H(2)O = ADP + phosphate + 2-
CC       (formamido)-N(1)-(5-phospho-D-ribosyl)acetamidine + L-glutamate.
CC       {ECO:0000256|HAMAP-Rule:MF_01926}.
CC   -!- PATHWAY: Purine metabolism; IMP biosynthesis via de novo pathway;
CC       5-amino-1-(5-phospho-D-ribosyl)imidazole from N(2)-formyl-N(1)-(5-
CC       phospho-D-ribosyl)glycinamide: step 1/2. {ECO:0000256|HAMAP-
CC       Rule:MF_01926}.
CC   -!- SUBUNIT: Part of the FGAM synthase complex composed of 1 PurL, 1
CC       PurQ and 2 PurS subunits. {ECO:0000256|HAMAP-Rule:MF_01926}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01926}.
CC   -!- SIMILARITY: Belongs to the PurS family. {ECO:0000256|HAMAP-
CC       Rule:MF_01926}.
