Isothermal Titration Calorimetry: Thermodynamic Analysis of the Binding Thermograms...
We have evaluated the strength of aromatic donor-acceptor interactions between dialkyl naphthalenediimide and dialkoxynaphthalene in non-polar environments. (1)H NMR, UV-vis spectroscopy and isothermal titration calorimetry were used to characterise this interaction. We concluded that the strength of donor-acceptor interactions in heptane is sufficient to drive supramolecular assemblies in this...
Dehydrocholic acid was identified as a selective streptavidin binder from a PNA-tagged library. Isothermal calorimetry titration measurements showed this interaction to be entropically driven. Peptides tagged with dehydrocholic acid can be captured on a streptavidin resin and released under thermal conditions.
The hammerhead ribozyme undergoes a well-defined two-stage conformational folding process, induced by the binding of magnesium ions. In this study, we have used isothermal titration calorimetry to analyze the thermodynamics of magnesium binding and magnesium ion-induced folding of the ribozyme. Binding to the natural sequence ribozyme is strongly exothermic and can be analyzed in terms of seque...
Enzymes, the catalysts of biological systems, are remarkable molecular devices that determine the patterns of chemical transformations. For many decades, a great deal of pure and applied studies have been devoted to enzyme reactions, as the mechanisms underlying the special characteristics of the reactions, such as high specificity and high efficiency, have not only attracted scientific interes...
