I am trying to set up a Glide grid with an H-bond constraint. When I click on the side chain N of Lys, Maestro says "WARNING This type of atom cannot be used as a Glide constraint". How do I add it as a constraint?
The LYS nitrogen cannot be the acceptor atom for an H-bond constraint (which is what clicking the heavy atom is requesting) unless it is the neutral -NH2 form. If you want the nitrogen to be the donor of its attached hydrogens, click one of the hydrogen atoms instead of the nitrogen atom.
