1 蛋白单体 单体 蛋白 × 1 PDB 声明:monomeric(1) 与蛋白拷贝数一致 链 B; UniProt 293–887 片段:UNP residues 293-887 GOL GLYCEROL × 1 2UG 4'-(cyclopropylmethyl)-N~2~-(pyridin-4-yl)-4,5'-bipyrimidine-2,2'-diamine × 1 X-RAY DIFFRACTION X-ray结晶条件:VAPOR DIFFUSION, HANGING DROP;303.15 K;VPS34 protein and PIK-III were mixed and incubated on ice for 1 hr (final PIK-III concentration was 1 mM). Prior to crystallization, the mixture was passed through a 0.2 um filter. The protein:ligand complex was crystallized using the hanging drop vapor diffusion method in Nextal plates: 6 uL of protein solution was mixed with 4 uL of precipitant, which consisted of 20% (w/v) PEG 3350, 100 mM bis-tris propane, and 200 mM Na-K-phosphate. The resulting drop was suspended over a reservoir of 0.3 mL of precipitant and sealed with a screw cap. The crystals grew at 30 degC in approximately 12-24 hr. 分辨率 2.80 Å R-free 0.223
