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}.
