GraDeR: Membrane Protein Complex Preparation for Single-Particle Cryo-EM.
We developed a method, named GraDeR, which substantially improves the preparation of membrane protein complexes for structure determination by single-particle cryo-electron microscopy (cryo-EM). In GraDeR, glycerol gradient centrifugation is used for the mild removal of free detergent monomers and micelles from lauryl maltose-neopentyl glycol detergent stabilized membrane complexes, resulting i...
متن کاملSingle-Particle Cryo-EM at Crystallographic Resolution
Until only a few years ago, single-particle electron cryo-microscopy (cryo-EM) was usually not the first choice for many structural biologists due to its limited resolution in the range of nanometer to subnanometer. Now, this method rivals X-ray crystallography in terms of resolution and can be used to determine atomic structures of macromolecules that are either refractory to crystallization o...
متن کاملSerial crystallography using synchrotron radiation
A brief history is given of how X-ray diffraction data from crystals have been recorded. Today there are new possibilities, spawned by the availability of free electron lasers that produce powerful femtosecond long X-ray pulses.
متن کاملFrealign: An Exploratory Tool for Single-Particle Cryo-EM.
Frealign is a software tool designed to process electron microscope images of single molecules and complexes to obtain reconstructions at the highest possible resolution. It provides a number of refinement parameters and options that allow users to tune their refinement to achieve specific goals, such as masking to classify selected regions within a particle, control over the refinement of spec...
متن کاملMix-and-diffuse serial synchrotron crystallography
Unravelling the interaction of biological macromolecules with ligands and substrates at high spatial and temporal resolution remains a major challenge in structural biology. The development of serial crystallography methods at X-ray free-electron lasers and subsequently at synchrotron light sources allows new approaches to tackle this challenge. Here, a new polyimide tape drive designed for mix...
