Abstract

Over the past few years, the advances in technology and methods that have revolutionized cryo-EM are allowing for key insights in a variety of areas in biology, and microbiology is no exception. A wide range of important macromolecular assemblies in prokaryotic and eukaryotic cells, as well as intact viruses, have now become accessible to investigation by new methods in 3D electron microscopy. We focus here on selected examples that illustrate this breadth, and review the application of methods in single particle cryo-EM and cryo-electron tomography to progress in the structural biology of CRISPR systems, visualization of small molecule drugs in membrane proteins, in situ visualization of bacterial nanomachines, and the analysis of antigen-antibody interactions to drive vaccine design.
