TOHO1 Beta lactamase mutant E166A/R274N/R276N -benzyl penicillin complex
Crystallization Crystalization Experiments ID Method pH Temperature Details 1 BATCH MODE 6.1 293.15 30 microliters of 10 mg/ml protein concentration was added to a solution containing 2.0 M ammonium sulfate and 0.1 M sodium citrate (pH 6.1). For ligand soaking, crystals were placed for 2-3 h in a reservoir solution containing 2.7 M ammonium sulfate, 0.1 M sodium citrate (pH 6.1), and 5.0 mM benzyl penicillin. The crystals were then placed momentarily in a reservoir solution containing a cryoprotectant (30% w/v trehalose) and subsequently flash-frozen in liquid nitrogen
