CC   -!- FUNCTION: Reduction of activated sulfate into sulfite.
CC   -!- CATALYTIC ACTIVITY: Adenosine 3',5'-bisphosphate + sulfite +
CC       thioredoxin disulfide = 3'-phosphoadenylyl sulfate + thioredoxin.
CC   -!- PATHWAY: Sulfur metabolism; hydrogen sulfide biosynthesis; sulfite
CC       from sulfate: step 3/3.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity).
CC   -!- SIMILARITY: Belongs to the PAPS reductase family. CysH subfamily.
