CC -!- FUNCTION: Phosphoribosylformylglycinamidine synthase involved in the
CC purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of
CC formylglycinamide ribonucleotide (FGAR) and glutamine to yield
CC formylglycinamidine ribonucleotide (FGAM) and glutamate.
CC {ECO:0000255|HAMAP-Rule:MF_00419}.
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:0000255|HAMAP-
CC Rule:MF_00419};
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:0000255|HAMAP-
CC Rule:MF_00419}.
CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_00419}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00419}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the FGAMS family.
CC {ECO:0000255|HAMAP-Rule:MF_00419}.
