Throw the water away, so you have two coordinate files, one of protein
and one of crystal each in the same format. You can translate and rotate
these with editconf if you want. Then you can literally concatenate them
in a text editor, taking care to preserve formats correctly (e.g. .gro
requires the number of atoms given in the first few lines is correct).
Then box with editconf and solvate with genbox. Before you start, obtain
.itp files for each type of molecule, which you can now use to build a
.top file by hand (using pdb2gmx will probably fail or make headaches).
Alternatively, some "docking" software may offer some automation, or
ways to generate a series of possible orientations.
