Shigella sonnei (strain Ss046)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

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 (purL)
  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.
