GBPs are dynamin-like GTPases that act as core orchestrators of the cell-autonomous immune response by coating the membranes of intracellular pathogen replication niches and/or cytosol-invasive gram-negative bacteria. We used cryo-EM/cryo-ET to resolve the molecular ultrastructure of GBP1 coatomers and reveal the large-scale conformational changes that allow GBP1 to selectively target LPS-containing membranes. We further demonstrate, for the first time, that GTP hydrolysis drives GBP1-dependent membrane fragmentation, which possibly underlies the ability to recruit and activate caspase4-dependent inflammasomes.

Gas vesicles are nanoscale buoyancy compartments that form a unique motility system in (aquatic) bacteria and archaea. Using cryo-EM, we reveal the first molecular structure of the intact gas vesicle shell at 3.2 Å resolution. Our structure explains the molecular details underlying their unique properties such as the selective permeability of the shell and the role of structural reinforcement elements, consolidating decades of biochemical and biophysical studies. Our structure also allows to formulate a testable hypothesis of the intrigiuing structural program of gas vesicle assembly and growth.

We have developed a microelectromechanical system (MEMS) in which macromolecular targets are enclosed in nanofluidic channels formed between ultrathin, electron-transparent membranes. We show that these devices are suitable for high-resolution 3D structure determination of macromolecular complexes from picoliter sample volumes. Our device protects the sample from a destructive air-water interface and provides excellent control over geometric parameters of the nanochannels which yields uniform ice thickness.

Methods to improve interpretation of electrostatic potential maps from cryo-EM reconstructions are essential to build accurate atomic models. For all downstream applications it is important that any form of manipulation of these maps retains the physical properties expected from scattering of biological macromolecules. In this article we provide a roadmap to utilising such information to restrain the process of map sharpening and discuss its potential and limitations.
