CATALYTIC ACTIVITY: ATP + sulfate = diphosphate + adenylyl sulfate.

PATHWAY: Sulfur metabolism; hydrogen sulfide biosynthesis; sulfite from sulfate: step 1/3.

SUBUNIT: Heterodimer composed of cysD, the smaller subunit, and cysN (By similarity).

SIMILARITY: Belongs to the PAPS reductase family. CysD subfamily.
