ID 1.8.4.10 DE Adenylyl-sulfate reductase (thioredoxin). AN Thioredoxin-dependent 5'-adenylylsulfate reductase. CA AMP + sulfite + thioredoxin disulfide = 5'-adenylyl sulfate + CA thioredoxin. CC -!- Uses adenylyl sulfate, not phosphoadenylyl sulfate, distinguishing CC this enzyme from EC 1.8.4.8. CC -!- Uses thioredoxin as electron donor, not glutathione or other donors, CC distinguishing it from EC 1.8.4.9 and EC 1.8.99.2. //
