Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the reversible conversion of ribose-5-phosphate to ribulose 5-phosphate.UniRule annotation

Catalytic activityi

D-ribose 5-phosphate = D-ribulose 5-phosphate.UniRule annotation

Pathwayi: pentose phosphate pathway

This protein is involved in step 1 of the subpathway that synthesizes D-ribose 5-phosphate from D-ribulose 5-phosphate (non-oxidative stage).UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Ribose-5-phosphate isomerase A (rpiA)
This subpathway is part of the pathway pentose phosphate pathway, which is itself part of Carbohydrate degradation.
