Citation | Journal: Nat Struct Mol Biol / Year: 2025Title: The human ribosome modulates multidomain protein biogenesis by delaying cotranslational domain docking. Authors: Grant A Pellowe / Tomas B Voisin / Laura Karpauskaite / Sarah L Maslen / Alžběta Roeselová / J Mark Skehel / Chloe Roustan / Roger George / Andrea Nans / Svend Kjær / Ian A Taylor / David Balchin / ![]() Abstract: Proteins with multiple domains are intrinsically prone to misfold, yet fold efficiently during their synthesis on the ribosome. This is especially important in eukaryotes, where multidomain proteins ...Proteins with multiple domains are intrinsically prone to misfold, yet fold efficiently during their synthesis on the ribosome. This is especially important in eukaryotes, where multidomain proteins predominate. Here we sought to understand how multidomain protein folding is modulated by the eukaryotic ribosome. We used hydrogen-deuterium exchange mass spectrometry and cryo-electron microscopy to characterize the structure and dynamics of partially synthesized intermediates of a model multidomain protein. We find that nascent subdomains fold progressively during synthesis on the human ribosome, templated by interactions across domain interfaces. The conformational ensemble of the nascent chain is tuned by its unstructured C-terminal segments, which keep interfaces between folded domains in dynamic equilibrium until translation termination. This contrasts with the bacterial ribosome, on which domain interfaces form early and remain stable during synthesis. Delayed domain docking may avoid interdomain misfolding to promote the maturation of multidomain proteins in eukaryotes. #1: Journal: Acta Crystallogr D Struct Biol / Year: 2019 Title: Macromolecular structure determination using X-rays, neutrons and electrons: recent developments in Phenix. Authors: 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 ...Authors: 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 / ![]() Abstract: 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. | |||||||||||||||
