CC -!- FUNCTION: Part of the phosphoribosylformylglycinamidine synthase
CC complex involved in the purines biosynthetic pathway. Catalyzes the
CC ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and
CC glutamine to yield formylglycinamidine ribonucleotide (FGAM) and
CC glutamate. The FGAM synthase complex is composed of three subunits.
CC PurQ produces an ammonia molecule by converting glutamine to glutamate.
CC PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP-
CC dependent manner. PurS interacts with PurQ and PurL and is thought to
CC assist in the transfer of the ammonia molecule from PurQ to PurL.
CC {ECO:0000256|HAMAP-Rule:MF_00420}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O + L-glutamine + N(2)-formyl-N(1)-(5-phospho-beta-D-
CC ribosyl)glycinamide = 2-formamido-N(1)-(5-O-phospho-beta-D-
CC ribosyl)acetamidine + ADP + H(+) + L-glutamate + phosphate;

CC ChEBI:CHEBI:456216; EC=6.3.5.3; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_00420};
CC -!- PATHWAY: Purine metabolism; IMP biosynthesis via de novo pathway; 5-
CC 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_00420}.
CC -!- SUBUNIT: Monomer. Part of the FGAM synthase complex composed of 1 PurL,
CC 1 PurQ and 2 PurS subunits. {ECO:0000256|HAMAP-Rule:MF_00420}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00420}.
CC -!- SIMILARITY: Belongs to the FGAMS family. {ECO:0000256|HAMAP-
CC Rule:MF_00420}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00420}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
