Accepted name: adenylyl-sulfate reductase (glutathione)
Reaction: AMP + sulfite + glutathione disulfide = adenylyl sulfate + 2 glutathione
Other name(s): 5′-adenylylsulfate reductase (also used for EC; AMP,sulfite:oxidized-glutathione oxidoreductase (adenosine-5′-phosphosulfate-forming); plant-type 5′-adenylylsulfate reductase
Systematic name: AMP,sulfite:glutathione-disulfide oxidoreductase (adenosine-5′-phosphosulfate-forming)
Comments: This enzyme differs from EC, adenylyl-sulfate reductase, in using glutathione as the reductant. Glutathione can be replaced by γ-glutamylcysteine or dithiothreitol, but not by thioredoxin, glutaredoxin or mercaptoethanol. The enzyme from the mouseear cress, Arabidopsis thaliana, contains a glutaredoxin-like domain. The enzyme is also found in other photosynthetic eukaryotes, e.g., the Madagascar periwinkle, Catharanthus roseus and the hollow green seaweed, Enteromorpha intestinalis.
