CC -!- FUNCTION: Catalyzes the transfer of a formyl group from 10-
CC formyltetrahydrofolate to 5-phospho-ribosyl-glycinamide (GAR),
CC producing 5-phospho-ribosyl-N-formylglycinamide (FGAR) and
CC tetrahydrofolate. {ECO:0000256|HAMAP-Rule:MF_01930}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(6R)-10-formyltetrahydrofolate + N(1)-(5-phospho-beta-D-
CC ribosyl)glycinamide = (6S)-5,6,7,8-tetrahydrofolate + H(+) + N(2)-
CC formyl-N(1)-(5-phospho-beta-D-ribosyl)glycinamide;
CC Xref=Rhea:RHEA:15053, ChEBI:CHEBI:15378, ChEBI:CHEBI:57453,
CC ChEBI:CHEBI:143788, ChEBI:CHEBI:147286, ChEBI:CHEBI:195366;
CC EC=2.1.2.2; Evidence={ECO:0000256|HAMAP-Rule:MF_01930};
CC -!- PATHWAY: Purine metabolism; IMP biosynthesis via de novo pathway; N(2)-
CC formyl-N(1)-(5-phospho-D-ribosyl)glycinamide from N(1)-(5-phospho-D-
CC ribosyl)glycinamide (10-formyl THF route): step 1/1.
CC {ECO:0000256|ARBA:ARBA00005054, ECO:0000256|HAMAP-Rule:MF_01930}.
CC -!- SIMILARITY: Belongs to the GART family. {ECO:0000256|HAMAP-
CC Rule:MF_01930}.
