Function and Biology Details

Reactions catalysed: 
10-formyltetrahydrofolate + N(1)-(5-phospho-D-ribosyl)glycinamide = tetrahydrofolate + N(2)-formyl-N(1)-(5-phospho-D-ribosyl)glycinamide
ATP + 2-(formamido)-N(1)-(5-phospho-D-ribosyl)acetamidine = ADP + phosphate + 5-amino-1-(5-phospho-D-ribosyl)imidazole
ATP + 5-phospho-D-ribosylamine + glycine = ADP + phosphate + N(1)-(5-phospho-D-ribosyl)glycinamide
