Protein
Glutathione amide reductase
Organism
Marichromatium gracile
Function
Catalyzes the reduction of glutathione amide disulfide (GASSAG) to restore glutathione amide (GASH) in the presence of NADH. May play a role in GASH metabolism under anaerobic conditions as a sulfide carrier necessary for cytoplasmic sulfide oxidation.
Similarity
Belongs to the class-I pyridine nucleotide-disulfide oxidoreductase family.
