This protein is involved in step 4 of the subpathway that synthesizes D-xylulose 5-phosphate from L-ascorbate.UniRule annotation
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. Probable L-ascorbate-6-phosphate lactonase UlaG (ulaG)
  2. 3-keto-L-gulonate-6-phosphate decarboxylase UlaD (ulaD)
  3. L-ribulose-5-phosphate 3-epimerase UlaE (ulaE)
  4. L-ribulose-5-phosphate 4-epimerase UlaF (ulaF)
This subpathway is part of the pathway L-ascorbate degradation, which is itself part of Cofactor degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes D-xylulose 5-phosphate from L-ascorbate, the pathway L-ascorbate degradation and in Cofactor 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.
