Structure preparation:

Base structure (6XTV_dock.pdb) obtained from PDB 6XTV chain B residues 89-290.

6XTV_A219L_dock.pdb was generated by using Dunbrack 2010 rotamer library to mutate residue 219 from A to L in UCSF Chimera. Then Chimera's AddH function was used to add hydrogens. 

PDBQT files prepared using prepare_receptor4.py from AutoDockTools.
