Function
function
Catalyzes the transfer of a formyl group from 10-formyltetrahydrofolate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR) and tetrahydrofolate.
Catalytic activity
- (6R)-10-formyltetrahydrofolate + N1-(5-phospho-beta-D-ribosyl)glycinamide = (6S)-5,6,7,8-tetrahydrofolate + H+ + N2-formyl-N1-(5-phospho-beta-D-ribosyl)glycinamide
Pathway
Purine metabolism; IMP biosynthesis via de novo pathway; N2-formyl-N1-(5-phospho-D-ribosyl)glycinamide from N1-(5-phospho-D-ribosyl)glycinamide (10-formyl THF route): step 1/1.
