CC -!- FUNCTION: Catalyzes the first intracellular reaction of sulfate
CC assimilation, forming adenosine-5'-phosphosulfate (APS) from inorganic
CC sulfate and ATP. Plays an important role in sulfate activation as a
CC component of the biosynthesis pathway of sulfur-containing amino acids.
CC {ECO:0000255|HAMAP-Rule:MF_03106}.
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_03106};
CC -!- PATHWAY: Sulfur metabolism; hydrogen sulfide biosynthesis; sulfite from
CC sulfate: step 1/3. {ECO:0000255|HAMAP-Rule:MF_03106}.
CC -!- SUBUNIT: Homohexamer. Dimer of trimers. {ECO:0000255|HAMAP-
CC Rule:MF_03106}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03106}.
CC -!- DOMAIN: The oligomerization domain is distantly related to APS kinases,
CC but it is not functional and does not bind APS. It is required for
CC oligomerization of the enzyme, although the oligomerization state has
CC no effect on the catalytic activity of the enzyme. {ECO:0000255|HAMAP-
CC Rule:MF_03106}.
CC -!- SIMILARITY: Belongs to the sulfate adenylyltransferase family.
CC {ECO:0000255|HAMAP-Rule:MF_03106}.
