Application
Acetate kinase is used to phosphorylate acetate to acetyl phosphate. Acetate Kinase from Bacillus stearothermophilus has been used to study allosteric activation.[1] [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.[2]
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.[3] 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.[4]
Involved in the metabolism of propanoate, pyruvate and taurine.
Physical form
Contains Tris-HCl buffer.
Other Notes
One unit will phosphorylate 1.0 μmole of acetate to acetyl phosphate per min at pH 7.2 at 30 °C.

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

1. Acetate kinase [EC 2.7.2.1] from an thermophile, B. stearothermophilus, was purified and crystalized. 2. This enzyme was shown to be a tetramer of identical subunits which had a molecular weight of about 40,000. Amino acid analysis showed no SH

The anoxygenic green sulfur bacteria (GSBs) assimilate CO(2) autotrophically through the reductive (reverse) tricarboxylic acid (RTCA) cycle. Some organic carbon sources, such as acetate and pyruvate, can be assimilated during the phototrophic growth of the GSBs, in the presence of
