I want to do simulation of protein at pH 12, in this case experimentally

S- is it correct and how to set force field to this.
Some force fields (like the Amber parameter sets and some others) have the CYM
residue, which is the thiolate form of cysteine. Find which force fields have
this residue, read about their use, and make a choice based on what you find.
