You could do homology modeling of several homologs using
http://protein.cribi.unipd.it/Homer/ . Then calculate the electrostatics of the
homologs.
Better though would be actual structures. How much identity do the homologues
have? If they are so close that homology modeling works, then you may

Dear Qiang
A good example of just such a case is acetylcholinesterase,
where homologous proteins have very similar electrostatic motifs,
with an very large electric dipole, ~1,700.
see three representative papers on this,

Hi all,
I'm working on a protein structure which showed a special electrostatic
potential on its surface: positive on one end and negative on the other
end. I wonder to what extent I can say this pattern is determined by the
charged residues? If the residues are conserved, could I make a conclusio
