RL Submitted (MAY-2006) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Involved in the de novo purine biosynthesis. Catalyzes the
CC transfer of formate to 5-phospho-ribosyl-glycinamide (GAR), producing
CC 5-phospho-ribosyl-N-formylglycinamide (FGAR). Formate is provided by
CC PurU via hydrolysis of 10-formyl-tetrahydrofolate. {ECO:0000255|HAMAP-
CC Rule:MF_01643}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + formate + N(1)-(5-phospho-beta-D-ribosyl)glycinamide =
CC ADP + H(+) + N(2)-formyl-N(1)-(5-phospho-beta-D-ribosyl)glycinamide +
CC phosphate; Xref=Rhea:RHEA:24829, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:15740, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:143788, ChEBI:CHEBI:147286, ChEBI:CHEBI:456216;
CC EC=6.3.1.21; Evidence={ECO:0000255|HAMAP-Rule:MF_01643};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:24830;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01643};
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 (formate route): step 1/1. {ECO:0000255|HAMAP-
CC Rule:MF_01643}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01643}.
CC -!- SIMILARITY: Belongs to the PurK/PurT family. {ECO:0000255|HAMAP-
CC Rule:MF_01643}.
