Dear Amber users,
I have a short peptide (about 30 residues) aminated in the C terminal. When I load it in xleap program, it tells me: there is no defined type for heavy atom N. In order to produce corresponding topology and coordinate file, I have to delete it, and atom OXT was then added.
Because this NH2 from aminated residues in the C terminal is important to interact with Receptor, another protein. Then how will I resolve such question for retaining NH2 during using SAVEAMBERPARM? Then I can use MD for my docked protein complex.
I am not a experienced user, and expect your help! Thanks a lot in advance!
Best Regards,
