In enzymology a phosphoadenylyl-sulfate reductase (thioredoxin) (EC 1.8.4.8) is an enzyme that catalyzes the chemical reactionadenosine 3’5′-bisphosphate + sulfite + thioredoxin disulfide 3′-phosphoadenylyl sulfate + thioredoxinThe 3 substrates of this enzyme are adenosine 3’5′-bisphosphate sulfite and thioredoxin disulfide whereas its two products are 3′-phosphoadenylyl sulfate and thioredoxin.This enzyme belongs to the family of oxidoreductases specifically those acting on a sulfur group of donors with a disulfide as acceptor.
