Transition metal and ligand hyperfine coupling constants for paramagnetic vanadium and copper model complexes have been calculated using DFT methods that are available in commercial software packages. Variations in EPR parameters with ligand identity and ligand orientation are two of the trends that have been investigated with DFT calculations. For example, the systematic variation of the vanadium...
A three-dimensional model of the transmembrane domain of a neuronal-type nicotinic acetylcholine receptor (nAChR), (α4)2(β2)3, was constructed from a homology structure of the muscle-type nAChR recently determined by cryo-electron microscopy. The neuronal channel model was embedded in a fully hydrated DMPC lipid bilayer, and molecular-dynamics simulations were performed for 5ns. A comparative analysis...
