Functioni

Catalytic activityi

ATP + L(or D)-ribulose = ADP + L(or D)-ribulose 5-phosphate.UniRule annotation

Pathwayi: L-arabinose degradation via L-ribulose

This protein is involved in step 2 of the subpathway that synthesizes D-xylulose 5-phosphate from L-arabinose (bacterial route).UniRule annotation
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. L-arabinose isomerase (araA)
  2. Ribulokinase (araB)
  3. L-ribulose-5-phosphate 4-epimerase (araD)
This subpathway is part of the pathway L-arabinose degradation via L-ribulose, 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-xylulose 5-phosphate from L-arabinose (bacterial route), the pathway L-arabinose degradation via L-ribulose and in Carbohydrate degradation.

Similar proteinsi

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.
