General annotation (Comments)

Function	Involved in the activation of acetate to acetyl CoA and the secretion of acetate. During anaerobic growth of the organism, this enzyme is also involved in the synthesis of most of the ATP formed catabolically. HAMAP MF_00020
Catalytic activity	ATP + acetate = ADP + acetyl phosphate. HAMAP MF_00020 ATP + propanoate = ADP + propanoyl phosphate. HAMAP MF_00020
Pathway	Metabolic intermediate biosynthesis; acetyl-CoA biosynthesis; acetyl-CoA from acetate: step 1/2. HAMAP MF_00020
Subunit structure	Homodimer. HAMAP MF_00020
Subcellular location	Cytoplasm HAMAP MF_00020.
Sequence similarities	Belongs to the acetokinase family.
