Dear members Some times ago, I asked you about H-bonds visualization in homodimer. But I had additional questions following below. 1.How to detect monomer-monomer interactions, H-bonds, hydrophobic interactions and electrostatic interactions etc. And Which visualization- tool is best for visualizing them? 2.Are there any tools to predict quaternary structures and it's interaction sites from tertiary structures? Tell me please. /From H.Iiduka e-mail: haruo_ii at hotmail.com
