CRYSTALLIZATION (Commentary)
ORGANISM
UNIPROT
LITERATURE
hanging-drop vapour-diffusion method, crystal structure of native and acarbose-complexed mutant CGTase F283L and F283Y
-
hanging-drop vapour-diffusion method at 293 K. X-ray diffraction data are collected to 2.2 A. The crystal belongs to space group R3, with unit-cell parameters a = b = 211.6, c = 52.7 A
-
crystals soaked with maltose
-
hanging drop vapor diffusion technique. Cross-linked enzyme crystals can be useful biocatalysts because they are stable at elevated temperature, in organic solvents, and in the presence of enzyme inactivation surfactant. They also maintain their activity against protein-digesting enzyme
-
mutant Y167H, hanging drop vapor diffusion method, using 15% (w/v) PEG 4000, 0.05 M Tris-HCl, 0.1 M sodium acetate buffer, 25 mM Na2HPO4, 150 mM NaCl, 10 mM imidazole pH 8.5
mutant Y195I, hanging drop vapor diffusion method, using 0.2 M sodium acetate trihydrate, 0.1 M Tris hydrochloride pH 9.0, 30% (w/v) polyethylene glycol 4000, at 22°C
-
purified recombinant mutant S77P CGTase in 10 mM sodium acetate, pH 5.5, large crystals from 17-20%-saturated ammonium sulfate at room temperature in 100 mM HEPES, pH 7.6, or 100 mM HEPES, pH 7.8, or 100 mM Tris/HCl, pH 8.0, like the wild-type enzyme, crystals are soaked in 25% v/v glycerol and directly flash-cooled, or soaked in 2% w/v acarbose, 4% w/v maltohexaose and 25% glycerol in 20% saturated ammonium sulfate for 25 min followed by flash-cooling, X-ray diffraction structure determination and analysis at 1.6 A resolution
