Starting Model(s) Initial Refinement Model(s) Type Source Accession Code Details experimental model PDB 1MDO
Crystallization Crystalization Experiments ID Method pH Temperature Details 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 2. Puck: PSL-1009, Cryo: CRYO: 50% Crystallant + 50% MPD. 2mM PLP added prior to crystallization. Partial occupanyc of PLP-Lys182 adduct and PLP-Tris adduct. The structure factors were corrected for lattice translocation disorder which caused initial high Rfactors (~25%)
