CC -!- FUNCTION: Catalyzes the formation of sulfite from phosphoadenosine 5'-
CC phosphosulfate (PAPS) using thioredoxin as an electron donor.
CC {ECO:0000256|HAMAP-Rule:MF_00063}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[thioredoxin]-disulfide + adenosine 3',5'-bisphosphate + 2
CC H(+) + sulfite = 3'-phosphoadenylyl sulfate + [thioredoxin]-dithiol;
CC Xref=Rhea:RHEA:11724, Rhea:RHEA-COMP:10698, Rhea:RHEA-COMP:10700,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:17359, ChEBI:CHEBI:29950,
CC ChEBI:CHEBI:50058, ChEBI:CHEBI:58339, ChEBI:CHEBI:58343; EC=1.8.4.8;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00063};
CC -!- PATHWAY: Sulfur metabolism; hydrogen sulfide biosynthesis; sulfite from
CC sulfate: step 3/3. {ECO:0000256|HAMAP-Rule:MF_00063}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00063}.
CC -!- SIMILARITY: Belongs to the PAPS reductase family. CysH subfamily.
CC {ECO:0000256|ARBA:ARBA00009732, ECO:0000256|HAMAP-Rule:MF_00063}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00063}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
