Function
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
- ATP + formate + N1-(5-phospho-beta-D-ribosyl)glycinamide = ADP + H+ + N2-formyl-N1-(5-phospho-beta-D-ribosyl)glycinamide + phosphateThis reaction proceeds in the forward direction.
Pathway
Purine metabolism; IMP biosynthesis via de novo pathway; N2-formyl-N1-(5-phospho-D-ribosyl)glycinamide from N1-(5-phospho-D-ribosyl)glycinamide (formate route): step 1/1.
