1.8.4.10

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 1.8.4.8, phosphoadenylyl-sulfate reductase (thioredoxin). Uses thioredoxin as electron donor, not glutathione or other donors, distinguishing it from EC 1.8.4.9 [adenylyl-sulfate reductase (glutathione)] and EC 1.8.99.2 (adenylyl-sulfate reductase).
