Type: conference-abstract
Abstract: The effect of hydration on ATP hydrolysis energy has been evaluated using a model system, where ATP is hydrolyzed via the transfer of ATP from water to organic solvent, the hydrolysis in the organic solvent, and the transfer of ADP and P i from the organic solvent to water.In this model, alkyl amine-containing octanol was employed as a solvent, in which ATP, ADP and P i are highly soluble.Because the hydrolysis is not detectable in the organic solvent, the partitioning of ATP, ADP and P i between water and organic solvent was thermodynamically analyzed.Although the Gibbs energy of hydrolysis in the organic solvent is similar with that in water, ATP hydrolysis in the organic solvent is entropy-driven, as opposed to that the hydrolysis in water is enthalpy-driven.
