[ccp4bb] Calculation of the net charge of an electrostatic surface for secondary structural elements

2010-03-25 Thread Page, Rebecca
Dear CPP4 community, I am in search of a program that will calculate the net charge of an electrostatic surface formed by individual secondary structural elements (versus the entire protein) of a structure: for example, the net charge of the electrostatic surface of helices 2 and 3 versus,

Hello Rebecca, this is merely a guess, but I think, it should work. As you calculate the electrostatic surface potential in pymol, it uses apbs. apbs, if I remember correctly creates an intermediate PDB-file where the B-factor column is replaced with the partial charge of that atom. So if you
