3. LINKED RESIDUES

Up to 10 pairs of LINKED RESIDUES can be input, in the form:-

LINKED RESIDUES
---------------
HIS-ASP  <- Residue-pair 1
HOH-***  <- Residue-pair 2
         <- Residue-pair 3
         <- Residue-pair 4
         <- Residue-pair 5
         <- Residue-pair 6
         <- Residue-pair 7
         <- Residue-pair 8
         <- Residue-pair 9
         <- Residue-pair 10

Description:-

The above list defines which residues, not directly hydrogen-bonded to the ligand are to be included in the plot, provided they are hydrogen-bonded to a residue that is hydrogen-bonded to the ligand.

Each residue-pair shows: the residue-type hydrogen-bonded to the ligand, and the residue-type to be plotted if it is hydrogen-bonded to this first residue.

For example, "HIS-ASP" will include any Asp residues that are H-bonded to a His which is H-bonded to the ligand. More generally, "HIS-***" will show any residue H-bonded to the His. Similarly, "HOH-***" will include any residues in the protein that are connected to the ligand via a water molecule.
