1 蛋白单体 单体 蛋白 × 1 PDB 声明:monomeric(1) 与蛋白拷贝数一致 链 A; UniProt 48–447 片段:Catalytic domain: Residues 48-447 AFJ (2R,4S,5S)-N-butyl-4-hydroxy-2,7-dimethyl-5-{[N-(4-methylpentanoyl)-L-methionyl]amino}octanamide × 1 X-RAY DIFFRACTION X-ray结晶条件:1.0M Ammonium sulfate in water, pH 5.5, VAPOR DIFFUSION, HANGING DROP, temperature 292K. Protein stock was BACE MUT46B batch XII 8.5 mg/mL in 10mM Tris-HCl pH 7.4, 25mM NaCl, with a 5-fold excess of NVP-AFJ144-NX-2 added from a 50mM stock solution in 90% DMSO-D6 (1.8% DMSO in drop). A solution containing 1.2M Ammonium sulfate, 25% Glycerol, 1mM NVP-AFJ144-NX-2 and 1.8% DMSO was used as cryo-protectant 分辨率 1.97 Å R-free 0.223
