Comments [?]

FUNCTIONInvolved in the de novo purine biosynthesis. Catalyzes the transfer of formate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR). Formate is provided by PurU via hydrolysis of 10-formyl-tetrahydrofolate.
CATALYTIC ACTIVITY Reaction=N(1)-(5-phospho-beta-D-ribosyl)glycinamide + formate + ATP = N(2)-formyl-N(1)-(5-phospho-beta-D-ribosyl)glycinamide + ADP + phosphate + H(+); Xref=Rhea:RHEA:24829, ChEBI:CHEBI:15378, ChEBI:CHEBI:15740, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:143788, ChEBI:CHEBI:147286, ChEBI:CHEBI:456216; EC=6.3.1.21; PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:24830;
PATHWAYPurine metabolism; IMP biosynthesis via de novo pathway; N(2)- formyl-N(1)-(5-phospho-D-ribosyl)glycinamide from N(1)-(5-phospho-D- ribosyl)glycinamide (formate route): step 1/1.
SUBUNITHomodimer.
SIMILARITYBelongs to the PurK/PurT family.
