The apparent intrinsic clearance of 13 drugs has been determined using rat liver microsomes at three different concentrations of microsomal protein. The kinetics was studied using the in vitro half-life method. The nonspecific binding of these drugs to the microsomes was also studied under the same conditions, except for cofactor removal, using equilibrium… (More)
DNA supercoiling is an inherent consequence of twisting DNA and is critical for regulating gene expression and DNA replication. However, DNA supercoiling at a genomic scale in human cells is uncharacterized. To map supercoiling, we used biotinylated trimethylpsoralen as a DNA structure probe to show that the human genome is organized into supercoiling… (More)
The folding behaviour of the molecular torsion balance framework is rationalised by considering the effects of solvation using the alpha/beta H-bond parameter scheme for estimating the free energies of pairwise functional group interactions in solution.
Thermodynamic double-mutant cycles and triple-mutant boxes are widely employed for the experimental quantification of non-covalent interactions and cooperative effects in proteins. This review describes the application of these powerful methodologies to the study of non-covalent interactions in synthetic systems.
The ability to monitor DNA polymerase activity with single-nucleotide resolution has been the cornerstone of a number of advanced single-molecule DNA sequencing concepts. Toward this goal, we report the first observation of the base-by-base DNA polymerase activity with single-base resolution at the single-molecule level. We describe the design and… (More)
A supramolecular approach has been used to investigate the free energies of intermolecular aromatic stacking interactions. Chemical double mutant cycles have been used to measure the effect of a range of substituents on face-to-face stacking interactions with phenyl and pentafluorophenyl rings. Electrostatic effects dominate the trends in interaction energy.
One of the fundamental goals of molecular computing is to reproduce the tenets of digital logic, such as component modularity and hierarchical circuit design. An important step toward this goal is the creation of molecular logic gates that can be rationally wired into multi-level circuits. Here we report the design and functional characterization of a… (More)
Molecular interactions underlie the whole of chemistry and biology. This tutorial review illustrates the use of rotameric folding molecules, topoisomers, atropoisomers, and tautomers as molecular balances for quantifying non-covalent interactions. This intramolecular approach enables a wide variety of interactions to be examined with a degree of geometric… (More)
