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