Hi Sumitro, Yes, positive potential favors interaction with negative charges and vice versa. <http://plato.cgl.ucsf.edu/pipermail/chimera-users/2012-May/007591.html> For example, in this tutorial, Coulombic coloring shows a blue (positive potential) pocket binding a highly negatively charged ligand. <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/tutorials/surfprop.html> <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/tutorials/surfprop.html#esp> Elaine On May 21, 2012, at 5:12 PM, Sumitro Harjanto wrote:
Hi elaine, so can I say that blue surface (positive potential) is positively charged and has the tendency to attract negative charges?

Hi elaine, so does blue patch (positive interaction energy) mean positively charged or negatively charged surface?
