CC   -!- FUNCTION: With CysN forms the ATP sulfurylase (ATPS) that catalyzes the
CC       adenylation of sulfate producing adenosine 5'-phosphosulfate (APS) and
CC       diphosphate, the first enzymatic step in sulfur assimilation pathway.
CC       APS synthesis involves the formation of a high-energy phosphoric-
CC       sulfuric acid anhydride bond driven by GTP hydrolysis by CysN coupled
CC       to ATP hydrolysis by CysD. {ECO:0000255|HAMAP-Rule:MF_00064}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H(+) + sulfate = adenosine 5'-phosphosulfate +
CC         diphosphate; Xref=Rhea:RHEA:18133, ChEBI:CHEBI:15378,

CC         Rule:MF_00064};
CC   -!- PATHWAY: Sulfur metabolism; hydrogen sulfide biosynthesis; sulfite from
CC       sulfate: step 1/3. {ECO:0000255|HAMAP-Rule:MF_00064}.
CC   -!- SUBUNIT: Heterodimer composed of CysD, the smaller subunit, and CysN.
CC       {ECO:0000255|HAMAP-Rule:MF_00064}.
CC   -!- SIMILARITY: Belongs to the PAPS reductase family. CysD subfamily.
