Protein

Probable ribose-5-phosphate isomerase 3, chloroplastic

Gene

RPI3

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the reversible conversion of ribose-5-phosphate to ribulose 5-phosphate.By similarity

Catalytic activityi

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

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).
Proteins known to be involved in this subpathway in this organism are:
  1. Probable ribose-5-phosphate isomerase 4, chloroplastic (RPI4), Probable ribose-5-phosphate isomerase 3, chloroplastic (RPI3), Probable ribose-5-phosphate isomerase 1 (RPI1), Probable ribose-5-phosphate isomerase 2 (RPI2)
This subpathway is part of the pathway pentose phosphate pathway, which is itself part of Carbohydrate degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes D-ribose 5-phosphate from D-ribulose 5-phosphate (non-oxidative stage), the pathway pentose phosphate pathway and in Carbohydrate degradation.
