ENZYME entry: EC 1.8.4.9

Accepted Name
Adenylyl-sulfate reductase (glutathione).
Alternative Name(s)
5'-adenylylsulfate reductase.
AMP,sulfite:oxidized-glutathione oxidoreductase (adenosine- 5'-phosphosulfate-forming).
Plant-type 5'-adenylylsulfate reductase.
Reaction catalysed
AMP + sulfite + glutathione disulfide <=> adenylyl sulfate + 2 glutathione
Comment(s)
  • Differs from EC 1.8.99.2, in using glutathione as the reductant.
  • Glutathione can be replaced by gamma-glutamylcysteine or dithiothreitol, but not by thioredoxin, glutaredoxin or 2-sulfanylethan-1-ol (2-mercaptoethanol).
  • The enzyme from Arabidopsis thaliana contains a glutaredoxin-like domain.
  • Also found in other photosynthetic eukaryotes, e.g., the Madagascar periwinkle, Catharanthus roseus and the hollow green seaweed, Enteromorpha intestinalis.
