CC   -!- FUNCTION: Involved in acetate metabolism. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=acetyl-CoA + phosphate = acetyl phosphate + CoA;
CC         Xref=Rhea:RHEA:19521, ChEBI:CHEBI:22191, ChEBI:CHEBI:43474,
CC         ChEBI:CHEBI:57287, ChEBI:CHEBI:57288; EC=2.3.1.8;
CC   -!- PATHWAY: Metabolic intermediate biosynthesis; acetyl-CoA biosynthesis;
CC       acetyl-CoA from acetate: step 2/2.
CC   -!- SUBUNIT: Homohexamer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- DOMAIN: The N-terminal region seems to be important for proper
CC       quaternary structure. The C-terminal region contains the substrate-
CC       binding site (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: In the N-terminal section; belongs to the CobB/CobQ family.
CC       {ECO:0000305}.
CC   -!- SIMILARITY: In the C-terminal section; belongs to the phosphate
CC       acetyltransferase and butyryltransferase family. {ECO:0000305}.
