Functioni

Catalytic activityi

ATP + 2-(formamido)-N1-(5-phospho-D-ribosyl)acetamidine = ADP + phosphate + 5-amino-1-(5-phospho-D-ribosyl)imidazole.UniRule annotation

Pathwayi: IMP biosynthesis via de novo pathway

This protein is involved in step 2 of the subpathway that synthesizes 5-amino-1-(5-phospho-D-ribosyl)imidazole from N(2)-formyl-N(1)-(5-phospho-D-ribosyl)glycinamide.UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Phosphoribosylformylglycinamidine synthase subunit PurQ (purQ), Phosphoribosylformylglycinamidine synthase subunit PurL (purL), Phosphoribosylformylglycinamidine synthase subunit PurS (purS)
  2. Phosphoribosylformylglycinamidine cyclo-ligase (purM)
This subpathway is part of the pathway IMP biosynthesis via de novo pathway, which is itself part of Purine metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes 5-amino-1-(5-phospho-D-ribosyl)imidazole from N(2)-formyl-N(1)-(5-phospho-D-ribosyl)glycinamide, the pathway IMP biosynthesis via de novo pathway and in Purine metabolism.
