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. QUINONOID INTERMEDIATE WITH ALANINE WAS PREPARED BY SOAKING THE TPL CRYSTALS FOR 5 MIN IN THE STABILIZATION SOLUTION CONTAINING 40% POLY(ETHYLENE GLYCOL) 5000 MONOMETHYL ETHER, 50 MM TRIETHANOLAMINE BUFFER (PH 8.0), 0.25 M KCL, 0.2 MM PLP, 0.5 MM DTT AND 10 MM L-ALA. |
