THIS REMARK 280 COMPLEX WAS FORMED BY MIXING N-TERMINALLY HIS6-TAGGED PROTEIN REMARK 280 WITH C-TERMINALLY HIS6-TAGGED SBD IN 50 MM NA-HEPES, PH 7.5, 150 REMARK 280 MM KCL, 20 MM DTT AND 5% (V/V) GLYCEROL AT A MOLAR RATIO OF 1:4. REMARK 280 CRYSTALS OF THE COMPLEX (20 MG/ML) WERE OBTAINED BY MIXING 3 REMARK 280 MICROLITERS OF PROTEIN WITH 3 MICROLITERS OF CRYSTALLIZATION REMARK 280 SOLUTION (10% (V/V) POLYETHYLENE GLYCOL 4000, 10% (V/V) MPD AND REMARK 280 0.1M SODIUM CITRATE, PH 5.8) WITH 1 ML OF CRYSTALLIZATION REMARK 280 SOLUTION IN THE RESERVOIR. MANGANESE IONS WERE USED INSTEAD OF REMARK 280 MAGNESIUM REQUIRED FOR THE BINDING OF THIAMIN DIPHOSPHATE TO THE REMARK 280 ENZYME.
