ORGANISM
UNIPROT
LITERATURE
purified recombinant UGT51 alone and in complex with UDP-glucose, hanging drop vapor diffusion method, mixing of 20 mg/ml protein in 20 mM Tris-HCl, 500 mM NaCl, and 2 mM DTT, with reservoir solution containing 0.2 M ammonium acetate, 0.1 M HEPES, pH 7.5, 25% w/v PEG 3350 for the free enzyme, or containing 0.2 M MgCl2, 0.1 M Tris, pH 8.5, and 25% w/v PEG 3350 for the enzyme complex, receiving microcrystals, optimized crystallization protocol involves dispensing 0.0015 ml of 20 mg/ml protein and 0.001 ml of reservoir solution (containing 0.2 M MgCl2, 0.1 M Tris pH 8.5 and 25% w/v PEG 3350) and 500 nl of 0.001 diluted crystal seed stock solution, rod protein crystals appear after 3 days, 14°C, crystals are soaked in cryoprotectant solution with 5 mM UDP-glucose, X-ray diffraction structure determination and analysis at 2.77 A and 1.9 A resolutions, respectively, molecular replacement using the structure of GtfD (PDB ID 1rrv) as the search model, modeling
