초록

Our previous quantum mechanical calculations using polyalanine model systems showed that the monodipolemacrodipoleinteractions selectively stabilize α-helices and make it possible for α-helices to be formed inhydrophobic environment where the solvent effect is not available. The monodipole-macrodipole interactionsin α-helices were studied molecular mechanically using various point-charge systems available. The resultsshow that all the point-charge systems used in the calculations produce the monodipole-macrodipoleinteractions up to about 60% compared to the results of the quantum mechanical calculations. The results ofmolecular mechanical calculations are explained and discussed compared to the results of the quantummechanical calculations.
