Accepted name: phosphoadenylyl-sulfate reductase (thioredoxin)
Reaction: adenosine 3′,5′-bisphosphate + sulfite + thioredoxin disulfide = 3′-phosphoadenylyl sulfate + thioredoxin
Glossary: 3′-phosphoadenylyl sulfate = PAPS
Other name(s): PAPS reductase, thioredoxin-dependent; PAPS reductase; thioredoxin:adenosine 3′-phosphate 5′-phosphosulfate reductase; 3′-phosphoadenylylsulfate reductase; thioredoxin:3′-phospho-adenylylsulfate reductase; phosphoadenosine-phosphosulfate reductase; adenosine 3′,5′-bisphosphate,sulfite:oxidized-thioredoxin oxidoreductase (3′-phosphoadenosine-5′-phosphosulfate-forming)
Systematic name: adenosine 3′,5′-bisphosphate,sulfite:thioredoxin-disulfide oxidoreductase (3′-phosphoadenosine-5′-phosphosulfate-forming)
Comments: Specific for PAPS. The enzyme from Escherichia coli will use thioredoxins from other species.
