I just realized, that I phrased my question wrong, actually I wanted to calculate the average isoelectric constant of the proteins surface-amino acids in order to apply the most optimal buffer system to solubilize my protein.

Dear Csaba,
Sorry, Chimera does not calculate isoelectric points or constants, it only estimates charge in aqueous solution near neutral pH. You would need to find some other program to do what you want.

It is best to send Chimera questions to the chimera-users at cgl.ucsf.edu list, CC’d here.

Apologies if you got this message more than once, I was having trouble sending the e-mail.
