TtgR C137I I141W M167L F168Y mutant in complex with resveratrol
Starting Model(s) Initial Refinement Model(s) Type Source Accession Code Details experimental model PDB 7K1A
Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, HANGING DROP 6.5 293 Protein at 10.4 mg/ml (433 uM) incubated 30 min with 1 mM resveratrol dissolved in ethanol. 2 microliters of protein was mixed with 2 microliters of reservoir consisting of 12% MEPEG 2000, 5% MPD, 0.3 M MGCL2, 100 MM BISTRIS pH 6.5. The droplet was set on a siliconized glass cover slip to minimize loss of resveratrol.
