CRYSTALS 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 50 MM K-PHOSPHATE PH 8.0, 0.5 MM PLP, 1 MM 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. COMPLEX OF Y71F TPL WITH 3-FLUORO-L-TYROSINE WAS PREPARED BY SOAKING CRYSTALS IN THE STABILIZING SOLUTION CONTAINING 10 MM 3- FLUORO-L-TYROSINE FOR ABOUT 30 SECONDS. |
