LITERATURE
purified recombinant PigA in apoform and in complex with cofactor FAD or L-proline, sitting drop vapor diffusion method, mixing of 0.001 ml of 15 mg/ml protein in 100 mm NaCl and 50 mm Tris·HCl, pH 8.0, with 0.001 ml of reservoir solution containing 27% PEG 600, and 0.1 M Na-HEPES, pH 7.5, for the complex crystals FAD is added in a molar ratio of 3:1 ratio to the protein solution, and mixed with a reservoir solution containing 40% ethylene glycol and 0.1 M Na-acetate, pH 5.0; or 1.7 M (NH4)2SO4, 0.2 M NaCl, and 0.1 M sodium cacodylate, pH 6.5, for the proline-complex crystal the protein solution contains 7 mM L-proline in addition to FAD and crown ether, and the reservoir contains 1.9 M sodium malonate, pH 6.0. The Pro-Gly complex crystal is obtained by including 5 mM L-prolylglycine in the E244A protein solution, with a reservoir of 1.6 M (NH4)2SO4, 2% PEG 400, and 0.1 M citric acid, pH 4.0, X-ray diffraction structure determination and analysis at 1.3-2.55 A resolution, molecular replacement using the structure of butyryl-CoA dehydrogenase (PDB ID 4L1F) as a search model
