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).

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
