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, ECO:0000269|PubMed:2659070}.
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 Optimum pH is 7.2 with only 50% of this activity retains at pH 6.2 or
CC 8.0. {ECO:0000269|PubMed:2659070};
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 ECO:0000269|PubMed:2659070}.
CC -!- PTM: Both N-terminus methionine truncation and retention have been
CC observed for this protein. {ECO:0000269|PubMed:2659070}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the FGAMS family.
