Starting Model(s) Initial Refinement Model(s) Type Source Accession Code Details experimental model PDB 5D91 5D91,4O6M experimental model PDB 4O6M 5D91,4O6M
Crystallization Crystalization Experiments ID Method pH Temperature Details 1 LIPIDIC CUBIC PHASE 6 295 100 mM Sodium citrate, pH 6, 50 mM sodium chloride, 20 mM magnesium chloride hexahydrate, 22% PEG 400 (precipitant). Concentrated protein at 30-35 mg/ml was mixed with monoolein (Sigma) in a 1:1.5 protein to lipid ratio (w/w). Monoolein was doped with 2% CDP-DAG
