Method pH Temprature Details
X-RAY DIFFRACTION ? 296 Crystals of JTO-FL were grown via sitting-drop vapor diffusion using a crystallization buffer consisting of 20% PEG 3350 and 0.2 M NH4H2PO4 at 23 degrees C. Both diamond-shaped and plate-shaped crystals were generated in the same drop using these conditions, but only the plate-shaped crystals produced usable diffraction data. To generate JTO-FL:ligand complexes, crystals of apo JTO-FL were soaked with a tenfold molar excess of ligand for 10 days. Crystals were harvested and immediately flash cooled in liquid nitrogen.
