Microcalorimetric studies on the formation of magnesium complexes of adenine nucleotides

J P Belaich et al. Proc Natl Acad Sci U S A. 1969 Oct.

Abstract

Values for the thermodynamic quantities (DeltaF, DeltaH, DeltaS) in reactions in which complexes of adenine nucleotides with magnesium ion (ATPMg(--), ADPMg(-), AMPMg) are formed have been obtained by a microcalorimetric technique by using an isothermic Calvet's apparatus. Experimental values measured at ionic strength mu = 0.2 indicate that complex formation reactions are driven by the entropic factor and that stability of complexes increases with length of the phosphate chain.
