Crystals were harvested and soaked overnight in a solution containing 100 mM PCPT, 35% PEG 3350, 200 mM Mg2Cl and 1-2 mM TK-666 from a 100 mM DMSO stock. After soaking the crystals were cryoprotected by soaking for 15 minutes in compound-soak solution supplemented with 20% ethylene glycol. Cryoprotected crystals were mounted on nylon loops and flash-cooled in liquid nitrogen., VAPOR DIFFUSION, SITTING DROP |

COOT was used to inspect the model and electron density and BUSTER or REFMAC were used for macromolecular refinement calculations. Geometry of the model was analyzed with MolProbity and stereochemistry of the compound analyzed with MOGUL.
