Application
Acetate kinase is used to phosphorylate acetate to acetyl phosphate. Acetate Kinase from Bacillus stearothermophilus has been used to study allosteric activation. [32P]-acetyl phosphate was generated by incubating potassium acetate in the reaction mixture with acetate kinase from Sigma. This [32P]-acetyl phosphate was used to label BldM, BldM D-54N or BldM D-54A loci during the study of the effect of bldM gene on Streptomyces coelicolor development.
Biochem/physiol Actions
Acetate kinase plays an important role in glycolysis. Acetate kinase phosphorylates acetate in the presence of ATP and a divalent cation, which ultimately results in the production of acetyl-CoA. Acetate kinase is also involved in the metabolism of propanoate, pyruvate and taurine. Acetate Kinase from Bacillus stearothermophilus is a thermostable tetramer of identical subunits with molecular weight of 40,000 Da each. The enzyme does not have a -SH group and is composed of 36% β-structure, 21 % α-helix and 43 % unordered structure.
Involved in the metabolism of propanoate, pyruvate and taurine.
Unit Definition

Fructose 1,6-bisphosphate (FBP) stimulates the reaction of Bacillus stearothermophilus acetate kinase (AK). FBP changes the reaction curve for ATP from a sigmoidal type to a Michaelis-Menten one. The binding of FBP to AK was studied by an equilibrium dialysis method
