In enzymology, a phosphoadenylyl-sulfate reductase (thioredoxin) () is an enzyme that catalyzes the chemical reaction :adenosine 3',5'-bisphosphate + sulfite + thioredoxin disulfide 3'-phosphoadenylyl sulfate + thioredoxin The 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. The systematic name of this enzyme class is adenosine 3',5'-bisphosphate,sulfite:thioredoxin-disulfide oxidoreductase (3'-phosphoadenosine-5'-phosphosulfate-forming). Other names in common use include 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, and oxidoreductase (3'-phosphoadenosine-5'-phosphosulfate-forming). This enzyme participates in sulfur metabolism. ==Structural studies== As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes , , and . 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Phosphoadenylyl-sulfate reductase (thioredoxin)」の詳細全文を読む スポンサード リンク
