The double-helical structure of DNA results from canonical base pairing and stacking interactions. However, variations from steady-state conformations result from mechanical perturbations in cells. These different topologies have physiological releva

The effect of spermine on the A-DNA to B-DNA transition in d(CGCGAATTCGCG)(2) has been investigated by five A-start molecular dynamics simulations, using the Cornell et al. potential. In the absence of spermine an A-->B transition is initiated immedi

Magnetic and optical tweezers have grown into a key tool when examining single molecules of DNA. However, it has not so far been possible to directly manipulate DNA through an applied force or torque while imaging its full contour length. In this wor

When DNA fibres are stretched during drying, the polymer undergoes a conformational transition. We present quantitative results from X-ray diffraction studies on such fibres held at various ambient relative humidities. These indicate that the molecul

A molecular dynamics simulation of the DNA dodecamer d(CGCATATATGCG) has been performed with AMBER 5.0 under low salt conditions. Both B → A and A → B transitions are observed. This may have biological significance for the formation of complexes

Molecular dynamics simulations with simulated annealing are performed on polyamine-DNA systems in order to determine the binding sites of putrescine, cadaverine, spermidine and spermine on A- and B-DNA. The simulations either contain no additional co

The direct methods program SAYTAN was applied to simulated data at various resolutions from three oligonucleotides. Success in solving the structures was found to depend more upon the resolution of the data than upon errors in the data or the complex

In this paper, the side-by-side model of DNA proposed by Premilat and Albiser is investigated. The axial repeat of the model is equal to the c-axis repeat in the observed B-DNA unit cell in fibres. However, the model does not pack into the unit cell

Simulated anomalous-scattering differences, at wavelengths between 1.5 and 5.5 A, were used with MULTAN to locate P atoms in an oligonucleotide hexamer. The success of the method depended heavily on the level of errors in the data. With error-free da

Molecular dynamics simulations of the cationic polyamine putrescine have been performed at T= 300 K. Partial charges of putrescine were calculated with both the HF/STO-3G and HF/6-3G* methods. Solvent was represented either explicitly or via a distan
