![]() | ![]() タイトル: MCM double hexamer loading visualized with human proteins. 著者: Florian Weissmann / Julia F Greiwe / Thomas Pühringer / Evelyn L Eastwood / Emma C Couves / Thomas C R Miller / John F X Diffley / Alessandro Costa / ![]() ![]() 要旨: Eukaryotic DNA replication begins with the loading of the MCM replicative DNA helicase as a head-to-head double hexamer at origins of DNA replication. Our current understanding of how the double ...Eukaryotic DNA replication begins with the loading of the MCM replicative DNA helicase as a head-to-head double hexamer at origins of DNA replication. Our current understanding of how the double hexamer is assembled by the origin recognition complex (ORC), CDC6 and CDT1 comes mostly from budding yeast. Here we characterize human double hexamer (hDH) loading using biochemical reconstitution and cryo-electron microscopy with purified proteins. We show that the human double hexamer engages DNA differently from the yeast double hexamer (yDH), and generates approximately five base pairs of underwound DNA at the interface between hexamers, as seen in hDH isolated from cells. We identify several differences from the yeast double hexamer in the order of factor recruitment and dependencies during hDH assembly. Unlike in yeast, the ORC6 subunit of the ORC is not essential for initial MCM recruitment or hDH loading, but contributes to an alternative hDH assembly pathway that requires an intrinsically disordered region in ORC1, which may work through a MCM-ORC intermediate. Our work presents a detailed view of how double hexamers are assembled in an organism that uses sequence-independent replication origins, provides further evidence for diversity in eukaryotic double hexamer assembly mechanisms, and represents a first step towards reconstitution of DNA replication initiation with purified human proteins. #1: ![]() タイトル: MCM Double Hexamer Loading Visualised with Human Proteins 著者: Weissmann, F. / Greiwe, J.F. / Puhringer, T. / Miller, T.C.R. / Diffley, J.F.X. / Costa, A. #2: ジャーナル: Acta Crystallogr D Struct Biol / 年: 2019 タイトル: Macromolecular structure determination using X-rays, neutrons and electrons: recent developments in Phenix. 著者: Dorothee Liebschner / Pavel V Afonine / Matthew L Baker / Gábor Bunkóczi / Vincent B Chen / Tristan I Croll / Bradley Hintze / Li Wei Hung / Swati Jain / Airlie J McCoy / Nigel W Moriarty / ...著者: Dorothee Liebschner / Pavel V Afonine / Matthew L Baker / Gábor Bunkóczi / Vincent B Chen / Tristan I Croll / Bradley Hintze / Li Wei Hung / Swati Jain / Airlie J McCoy / Nigel W Moriarty / Robert D Oeffner / Billy K Poon / Michael G Prisant / Randy J Read / Jane S Richardson / David C Richardson / Massimo D Sammito / Oleg V Sobolev / Duncan H Stockwell / Thomas C Terwilliger / Alexandre G Urzhumtsev / Lizbeth L Videau / Christopher J Williams / Paul D Adams / ![]() ![]() ![]() 要旨: Diffraction (X-ray, neutron and electron) and electron cryo-microscopy are powerful methods to determine three-dimensional macromolecular structures, which are required to understand biological ...Diffraction (X-ray, neutron and electron) and electron cryo-microscopy are powerful methods to determine three-dimensional macromolecular structures, which are required to understand biological processes and to develop new therapeutics against diseases. 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. | |||||||||||||||
