CC -!- FUNCTION: Catalyzes the formation of acetyl phosphate from acetate and
CC ATP. Can also catalyze the reverse reaction. {ECO:0000255|HAMAP-
CC Rule:MF_00020}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=acetate + ATP = acetyl phosphate + ADP; Xref=Rhea:RHEA:11352,
CC ChEBI:CHEBI:22191, ChEBI:CHEBI:30089, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:456216; EC=2.7.2.1; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00020};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00020};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00020};
CC Note=Mg(2+). Can also accept Mn(2+). {ECO:0000255|HAMAP-Rule:MF_00020};
CC -!- PATHWAY: Metabolic intermediate biosynthesis; acetyl-CoA biosynthesis;
CC acetyl-CoA from acetate: step 1/2. {ECO:0000255|HAMAP-Rule:MF_00020}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00020}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00020}.
CC -!- SIMILARITY: Belongs to the acetokinase family. {ECO:0000255|HAMAP-
CC Rule:MF_00020}.
