Hello
I want to simulate interaction of D-peptides with some proteins using MD and CHARMM force field.
As you know, the CHARMM force field for GROMACS is provided by MacKerell lab:
http://mackerell.umaryland.edu/charmm_ff.shtml#gromacs

Does the parameters of D-peptides are provided in CHARMM? and Does these parameters exist in the files of MacKerell lab?
