Adenylyl-sulfate reductase (thioredoxin)

Adenylyl-sulfate reductase (thioredoxin) () is an enzyme that catalyzes the chemical reaction
The 3 substrates of this enzyme are adenosine monophosphate, sulfite, and thioredoxin disulfide, whereas its two products are 5'-adenylyl sulfate and thioredoxin.
This enzyme belongs to the family of oxidoreductases, specifically those acting on a sulfur group of donors with a disulfide as acceptor. The systematic name of this enzyme class is AMP, sulfite:thioredoxin-disulfide oxidoreductase (adenosine-5'-phosphosulfate-forming). This enzyme is also called thioredoxin-dependent 5'-adenylylsulfate reductase.
