Thermostable omega transaminase PjTA-R6 variant W58G engineered for asymmetric synthesis of enantiopure bulky amines
Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, HANGING DROP 7.6 293 Drops were prepared by mixing 1 ul of protein solution (~10 mg/ml in 20 mM HEPES pH 7.5, 100 mM NaCl, 20 uM PLP buffer) with 1 ul of reservoir solution. Reservoir contained 0.7-1M succinic acid pH 7.6. Crystals appeared after 48h.
