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 -!- ACTIVITY REGULATION: Allosterically inhibited by 3'-phosphoadenosine
CC 5'-phosphosulfate (PAPS). {ECO:0000255|HAMAP-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 adenylyl-sulfate kinase (APS kinase) is non-functional. It
CC is involved in allosteric regulation by PAPS. PAPS binding induces a
CC large rotational rearrangement of domains lowering the substrate
CC affinity of the enzyme. {ECO:0000255|HAMAP-Rule:MF_03106}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the sulfate
CC adenylyltransferase family. {ECO:0000255|HAMAP-Rule:MF_03106}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the APS kinase
CC family. {ECO:0000255|HAMAP-Rule:MF_03106}.
