Hi Nikolay, No, sorry, there is nothing like that in Chimera. Sounds like you would need to use molecular simulation software (Amber, Gromacs, many others). Maybe you can ask on CCL.net if you want more advice, or on the email lists for specific simulation packages -- best, Elaine ----- Elaine C.

Hi all,

Is there any way in Chimera to model protein denaturation across various pH values?

Thanks Nikolay Rodionv
