1	VAPOR DIFFUSION, SITTING DROP	8.5	291	Proplex H12: 15% Ethanol, 5% MPD, 0.1M Tris pH 8.5, 0.1 M NaCl, KlaeA.17333.b.B1.PW39179 at 27 mg/mL. Plate: 13222, well H12 drop 3. Puck: PSL-1013, Cryo: CRYO: 50% Crystallant + 50% MPD. 2mM PLP added prior to crystallization. Partial occupancy of PLP-Lys182 adduct and PLP-Tris adduct. The structure factors were corrected for lattice translocation disorder which caused initial high R factors (~25%)
