Conformation and dynamics of a cyclic (1-->2)-beta-D-glucan.
A molecular modelling and nuclear magnetic resonance spectroscopic study was performed in order to gain insight into the conformational preferences of cyclosophoroheptadecaose. MM3 molecular mechanics calculations predicted a non-symmetric conformer with a small cavity of 3.7 A diameter as the lowest energy form. Molecular dynamics simulations gave insight into the dynamics of the free cyclosophoroheptadecaose and also supported the results of molecular mechanics calculations. A fair agreement was found between experimental data and corresponding average values predicted by molecular modelling.
