Protein

Probable glutathione transferase omega-2

Gene

gsto-2

Organism
Caenorhabditis briggsae
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Exhibits glutathione-dependent thiol transferase activity. Has dehydroascorbate reductase activity and may contribute to the recycling of ascorbic acid. Participates in the biotransformation of inorganic arsenic and reduces monomethylarsonic acid (MMA) (By similarity).By similarity

Catalytic activityi

RX + glutathione = HX + R-S-glutathione.
2 glutathione + dehydroascorbate = glutathione disulfide + ascorbate.
Methylarsonate + 2 glutathione = methylarsonite + glutathione disulfide + H2O.

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 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.
