EC - Adenylyl-sulfate reductase (thioredoxin)

  IntEnz view ENZYME view

IntEnz Enzyme Nomenclature


Accepted name:
adenylyl-sulfate reductase (thioredoxin)
Other name:
thioredoxin-dependent 5'-adenylylsulfate reductase
Systematic name:
AMP,sulfite:thioredoxin-disulfide oxidoreductase (adenosine-5'-phosphosulfate-forming)



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).
