Function
function
Phosphoribosylformylglycinamidine synthase involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate.
Catalytic activity
- ATP + H2O + L-glutamine + N2-formyl-N1-(5-phospho-beta-D-ribosyl)glycinamide = 2-formamido-N1-(5-O-phospho-beta-D-ribosyl)acetamidine + ADP + H+ + L-glutamate + phosphate
Pathway
Purine metabolism; IMP biosynthesis via de novo pathway; 5-amino-1-(5-phospho-D-ribosyl)imidazole from N2-formyl-N1-(5-phospho-D-ribosyl)glycinamide: step 1/2.
