Comments [?]

Function Involved 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 RHEA:24829: ATP + formate + N(1)-(5-phospho-beta-D-ribosyl)glycinamide = ADP + H(+) + N(2)-formyl-N(1)-(5-phospho-beta-D-ribosyl)glycinamide + phosphate
Pathway Purine 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.
Subunit Homodimer.
Similarity Belongs to the PurK/PurT family.
