Functioni

Catalytic activityi

10-formyltetrahydrofolate + 5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide = tetrahydrofolate + 5-formamido-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide.UniRule annotation
IMP + H2O = 5-formamido-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide.UniRule annotation

Pathwayi: IMP biosynthesis via de novo pathway

This protein is involved in step 1 of the subpathway that synthesizes 5-formamido-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide from 5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide (10-formyl THF route).UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Bifunctional purine biosynthesis protein PurH (purH)
This subpathway is part of the pathway IMP biosynthesis via de novo pathway, which is itself part of Purine metabolism.
