IUBMB Enzyme Nomenclature


Accepted name: adenylyl-sulfate reductase (thioredoxin)

Reaction: AMP + sulfite + thioredoxin disulfide = 5'-adenylyl sulfate + thioredoxin

Other name(s): thioredoxin-dependent 5'-adenylylsulfate reductase

Systematic name: AMP,sulfite:thioredoxin-disulfide oxidoreductase (adenosine-5'-phosphosulfate-forming)

Comments: Uses adenylyl sulfate, not phosphoadenylyl sulfate, distinguishing this enzyme from EC, phosphoadenylyl-sulfate reductase (thioredoxin). Uses thioredoxin as electron donor, not glutathione or other donors, distinguishing it from EC [adenylyl-sulfate reductase (glutathione)] and EC (adenylyl-sulfate reductase).
