  1. The numbers without parentheses are for non-minimized and the numbers in parentheses are for minimized complexes. The last two rows report the correlation coefficient and the slope of the fitting line of the graphs provided in Additional file 1. The calculations were done with probe radius 1.4A and internal dielectric constant of 2.0.
