Abstract

High-precision isothermal titration calorimetry is used for characterizing the binding of the monomer to Mg(II)-free and Mg(II)-bound adenosine nucleotides in order to understand the energetic basses governing the recognition of nucleotides by the isolated [beta] subunit from thermophilic Bacillus PS3 (T[beta]). A structural-energetic analysis has shown that T[beta] has adopted a more closed conformation when it is bound to Mg.ATP than to ATP or Mg.ADP.
