Term Name: phosphoadenylyl-sulfate reductase (thioredoxin) activity
Synonyms: 3'-phosphoadenylylsulfate reductase activity, adenosine 3',5'-bisphosphate,sulfite:oxidized-thioredoxin oxidoreductase (3'-phosphoadenosine-5'-phosphosulfate-forming), adenosine 3',5'-bisphosphate,sulfite:thioredoxin-disulfide oxidoreductase (3'-phosphoadenosine-5'-phosphosulfate-forming), PAdoPS reductase activity, PAPS reductase activity, PAPS reductase, thioredoxin-dependent activity, PAPS sulfotransferase activity, phosphoadenosine-phosphosulfate reductase activity, phosphoadenylyl-sulphate reductase (thioredoxin) activity, thioredoxin:3'-phospho-adenylylsulfate reductase activity, thioredoxin:adenosine 3'-phosphate 5'-phosphosulfate reductase activity
Definition: Catalysis of the reaction: adenosine 3',5'-diphosphate + H+ + sulfite + thioredoxin disulfide = 3'-phospho-5'-adenylyl sulfate + thioredoxin. Thioredoxin disulfide is the oxidized form of thioredoxin; 3'-phosphoadenosine 5'-phosphosulfate is also known as PAPS.
