CC -!- FUNCTION: With CysD 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_00062}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H(+) + sulfate = adenosine 5'-phosphosulfate +
CC diphosphate; Xref=Rhea:RHEA:18133, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:16189, ChEBI:CHEBI:30616, ChEBI:CHEBI:33019,
CC ChEBI:CHEBI:58243; EC=2.7.7.4; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00062};
CC -!- PATHWAY: Sulfur metabolism; hydrogen sulfide biosynthesis; sulfite from
CC sulfate: step 1/3. {ECO:0000255|HAMAP-Rule:MF_00062}.
CC -!- SUBUNIT: Heterodimer composed of CysD, the smaller subunit, and CysN.
CC {ECO:0000255|HAMAP-Rule:MF_00062}.
CC -!- SIMILARITY: Belongs to the TRAFAC class translation factor GTPase
CC superfamily. Classic translation factor GTPase family. CysN/NodQ
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_00062, ECO:0000305}.
