The overall structure-solution workflow is similar for these techniques, but nuances exist because the properties of the reduced experimental data are different. Software tools for structure determination should therefore be tailored for each method. Phenix is a comprehensive software package for macromolecular structure determination that handles data from any of these techniques. Tasks performed with Phenix include data-quality assessment, map improvement, model building, the validation/rebuilding/refinement cycle and deposition. Each tool caters to the type of experimental data. The design of Phenix emphasizes the automation of procedures, where possible, to minimize repetitive and time-consuming manual tasks, while default parameters are chosen to encourage best practice. A graphical user interface provides access to many command-line features of Phenix and streamlines the transition between programs, project tracking and re-running of previous tasks. #1: ![]() タイトル: MCM Double Hexamer Loading Visualised with Human Proteins 著者: Weissmann F / Greiwe JF / Puhringer T / Miller TCR / Diffley JFX / Costa A | |||||||||||||||

詳細 | The MCM recruitment reaction was reconstituted in vitro using purified H. sapiens proteins, a short DNA template and ATPgammaS. Four microlitres of the entire reaction was applied on a grid and incubated for 1 min at room temperature before blotting with filter paper for 5 s and plunge-freezing in liquid ethane. |
