[gmx-users] Mutation on membrane protein - Charmm36 for Gromacs

[CROUZY Serge 119222]

Hello Gromacs users 

I'd like to use Gromacs to find free energy change in a membrane protein upon single-residue mutation
Does anyone have proper forcefield files for doing this ?
LIke 
Charmm36_AA_MUTATION_FORCEFIELD for mutated proteins mixed with charmm36.ff_4.5.7 for lipids ?
(I've already got a membrane protein inserted in a membrane built and energy minimized with CHARMM)


This would be of GREAT help
