Your suggestion of setting the alt-loc the same for the two residues in order to avoid the non-bonded contact restraint is not working yet. Do the residues need to be in the same chain

So now I am modeling it as PLP and Lys. But there is some bridging density. I want to see how close the Lys would extend if it didn't see the PLP.
