Protein

Glutathione transferase omega-1

Gene

gsto-1

Organism
Caenorhabditis elegans
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Exhibits glutathione-dependent thiol transferase activity (By similarity). Has dehydroascorbate reductase activity and may contribute to the recycling of ascorbic acid (By similarity). Participates in the biotransformation of inorganic arsenic and reduces monomethylarsonic acid (MMA) (By similarity). Protects against environmental stress and oxidative stress (PubMed:17901115).By similarity1 Publication

Catalytic activityi

RX + glutathione = HX + R-S-glutathione.By similarity
2 glutathione + dehydroascorbate = glutathione disulfide + ascorbate.1 Publication
Methylarsonate + 2 glutathione = methylarsonite + glutathione disulfide + H2O.1 Publication

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.
