Hi,
I am planning to model a GFP protein. However, I could not find charmm parameters for the chromophore within charmm distribution. But, I found parameters derived by Reuter et al (https://doi.org/10.1021/jp014476w) to be widely used by others who worked with GFPs. My question is, since these parameters were derived using C22, can I use those parameters and model the rest of the protein with C36 parameters?
Thank you,
best,
