L-gulonolactone oxidase

Gene

Gulo

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Oxidizes L-gulono-1,4-lactone to hydrogen peroxide and L-xylo-hexulonolactone which spontaneously isomerizes to L-ascorbate.1 Publication

Catalytic activityi

L-gulono-1,4-lactone + O2 = L-ascorbate + H2O2.

Cofactori

Pathwayi: L-ascorbate biosynthesis via UDP-alpha-D-glucuronate pathway

This protein is involved in step 4 of the subpathway that synthesizes L-ascorbate from UDP-alpha-D-glucuronate.
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. no protein annotated in this organism
  3. Regucalcin (Rgn)
  4. L-gulonolactone oxidase (Gulo)
This subpathway is part of the pathway L-ascorbate biosynthesis via UDP-alpha-D-glucuronate pathway, which is itself part of Cofactor biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-ascorbate from UDP-alpha-D-glucuronate, the pathway L-ascorbate biosynthesis via UDP-alpha-D-glucuronate pathway and in Cofactor biosynthesis.

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.
