LITERATURE
purified enzyme in complex with glucose and phosphate and in complex with kojibiose and sulfate, Glc-PO4 crystals are obtained at 25°C by sitting drop vapor diffusion method, mixing 0.001 ml of 5.9 m/ml protein in 5 mM Tris/HCl, pH 7.5, with an equal volume of reservoir solution containing 5 mM D-glucose, 5 mM sodium phosphate, pH 8.5, 10% v/v 2-propanol, 10% w/v PEG 3350, and 0.1 M Tris/HCl, pH 8.5, the kojibiose-SO4 crystals are obtained at 25°C by hanging drop vapor diffusion method, mixing of 0.001 ml of 5.4 mg/ml protein solution in 5 mM Tris/HCl, pH 7.5, with an equal volume of reservoir solution containing 5 mM kojibiose, 0.2 M NaCl, 2.0 M (NH4)2SO4, and 0.1 M sodium cacodylate, pH 6.5, X-ray diffraction structure determination and analysis at 2.05-2.80 A resolution, structures PDB IDs 3WIR and 3WIQ, molecular replacement with the maltose phosphorylase structure from Lactobacillus brevis LbMP, PDB ID 1H54, as the search model
