The question has come up at least once before here - but are there parameters for N-methylated aminoacids in peptides in CHARMM36?

Or should I work with the charges from the CT3 patch and hope that these are not too far off? If I do do that, how about CMAP parameters?

My answer to this question is exactly the same as this one: we've done a full parametrization of the model compound N-methylalanine in a peptide/protein context, including CMAP. I won't post it here because the experimental validation and fine-tuning is still in progress (it got put on the backburner in favor of other projects), but if you send me a personal e-mail explaining what you want to use it for, I may share it with you.

Hi Kenno,

just sent you email.
