温度: 293 K / 手法: 蒸気拡散法, ハンギングドロップ法 / pH: 8 詳細: CRYSTALS OF THE C. FREUNDII TPL WERE GROWN AT 277 AND 293 K USING THE HANGING DROP VAPOR DIFFUSION METHOD.

THE BEST CRYSTALS WERE OBTAINED BY MIXING 2 UL OF THE PROTEIN SOLUTION (18-20 MG/ML) CONTAINING 50MM K-PHOSPHATE PH 8.0, 0.5 MM PLP, 1MM DDT WITH AN EQUAL VOLUME OF THE RESERVOIR SOLUTION CONTAINING 50 MM TRIETHANOLAMINE BUFFER (PH 8.0), 0.5 MM PLP, 2 MM DDT, 0.4 M KCL, AND 35-38% (W/V) POLY(ETHYLENE GLYCOL) 5000 MONOMETHYL ETHER. THE ALANINE QUINONOID COMPLEX WITH PYRIDINE N-OXIDE (9PO) WAS PREPARED BY SOAKING WILD TYPE TPL CRYSTALS IN THE STABILIZATION SOLUTION CONTAINING 40% (W/V) POLY(ETHYLENE GLYCOL) 5000 MONOMETHYL ETHER (PEG 5000 MME), 50 MM TRIETHANOLAMINE PH 8.0, 0.25 M KCL, 0.2 MM PYRIDOXAL 5-PHOSPHATE (PLP), 0.5 MM DITHIOTHREITOL (DTT), WITH ADDITION OF 100 MM L- ALANINE AND A SATURATING CONCENTRATION OF PYRIDINE N-OXIDE. SINCE THE CRYSTALS QUALITY DETERIORATED RAPIDLY, THE SOAKING TIME WAS RESTRICTED TO ABOUT 20 S.
