ジャーナル: J. Mol. Biol. / 年: 2001 タイトル: A 1.8 A resolution structure of pig muscle 3-phosphoglycerate kinase with bound MgADP and 3-phosphoglycerate in open conformation: new insight into the role of the nucleotide in domain closure. 著者: Szilagyi, A.N. / Ghosh, M. / Garman, E. / Vas, M.
温度: 288 K / 手法: 蒸気拡散法, ハンギングドロップ法 / pH: 7.7 詳細: THE ENZYME WAS DIALYSED IN 30 MM NAK-PHOSPHATE BUFFER, PH=8.0. SINGLE CRYSTALS WERE GROWN AT 15C WITHIN A FEW WEEKS IN HANGING DROPS (10-15 ML EACH) INITIALLY CONTAINING 1.25 M NAK-PHOSPHATE ...詳細: THE ENZYME WAS DIALYSED IN 30 MM NAK-PHOSPHATE BUFFER, PH=8.0. SINGLE CRYSTALS WERE GROWN AT 15C WITHIN A FEW WEEKS IN HANGING DROPS (10-15 ML EACH) INITIALLY CONTAINING 1.25 M NAK-PHOSPHATE (PH=8.0), 100 MM 3-PG, 25 MM MGCL2, 20 MM ADP, 10 MM DITHIOTHREITOL, 0.02% NAN3 AND 15 MG/ML PGK. RESERVOIR SOLUTIONS CONTAINED 2.4-2.75 M NAK-PHOSPHATE(PH=8.0)., pH 7.70
