I dont understand this - i have imposed NONX on water molecules in diff
chains so it cant be the non-solvent..
You have a diff CHAIN ID for each copy of the lipoamide, and each has
the same "residue number"?
ie ATOM ... LPM 639 P ....
then
ATOM ... LPM 639 Q
and
ATOM ... LPM 639 R
NONX 3 CHNID P Q R NSPANS 1 639 639 1
You will also need another NONX definition for the protein..
