  • Application of monolayer graphene to cryo-electron microscopy grids for high-resolution structure determination

    • Authors : Grassetti, andrew V (2023)

  • The application of support layers, such as graphene, to cryo-electron microscopy grids can increase the density of particles imaged, limit particle interactions with the air-water interface, reduce the extent of beam-induced motion, and, in some instances, improve the distribution of particle orientations. This paper describes a robust protocol for coating cryo-EM grids with a monolayer of graphene for improved cryo-sample preparation. Single particle cryo...

  • Structural Insights into the Iron Nitrogenase Complex

    • Authors : Schmidt, Frederik V.  (2023)

  • Nitrogenases are best known for catalysing the reduction of dinitrogen to ammonia at a complex metallic cofactor. Recently, nitrogenases were shown to reduce carbon dioxide (CO2) and carbon monoxide to hydrocarbons, offering a pathway to recycle carbon waste into hydrocarbon products. Among the nitrogenase family the iron nitrogenase is the isozyme with the highest wildtype activity for the reduction of CO2, but the molecular architecture facilitating these&#...
