| 1 | VAPOR DIFFUSION, SITTING DROP | 8 | 286 | Protein stock solution: 6 mg/mL PutA with 50 mM tetrahydrothiophene-2-carboxylate in a buffer containing 50 mM Tris (pH 8.0), 50 mM NaCl, 5% (w/v) glycerol, and 0.5 mM Tris(2-caboxyethyl)phosphine. Reservoir solution: 19 % PEG-3350, 0.2 M ammonium sulfate, 0.1 M magnesium chloride, 0.1 M HEPES (pH 8.0), and 0.1 M sodium formate. Cryo-buffer: reservoir supplemented with 15 % PEG-200. Crystals were grown in low-light conditions and then exposed to bright light before flash-cooling to induce the decarboxylation of tetrahydrothiophene-2-carboxylate and covalent modification of the FAD |
