CC -!- FUNCTION: Catalyzes the conversion of acetate into acetyl-CoA (AcCoA),
CC an essential intermediate at the junction of anabolic and catabolic
CC pathways. AcsA undergoes a two-step reaction. In the first half
CC reaction, AcsA combines acetate with ATP to form acetyl-adenylate
CC (AcAMP) intermediate. In the second half reaction, it can then transfer
CC the acetyl group from AcAMP to the sulfhydryl group of CoA, forming the
CC product AcCoA. {ECO:0000256|HAMAP-Rule:MF_01123}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=acetate + ATP + CoA = acetyl-CoA + AMP + diphosphate;
CC Xref=Rhea:RHEA:23176, ChEBI:CHEBI:30089, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:33019, ChEBI:CHEBI:57287, ChEBI:CHEBI:57288,
CC ChEBI:CHEBI:456215; EC=6.2.1.1; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_01123};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01123};
CC -!- PTM: Acetylated. Deacetylation by the SIR2-homolog deacetylase
CC activates the enzyme. {ECO:0000256|HAMAP-Rule:MF_01123}.
CC -!- SIMILARITY: Belongs to the ATP-dependent AMP-binding enzyme family.
CC {ECO:0000256|HAMAP-Rule:MF_01123}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01123}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
