The paper uses cryo-electron tomography and proteomics to study the structure and organisation of the type IX secretion system in Bacteroidetes, identifying new interactions and proposing a model for substrate secretion.

The paper identifies a novel widespread bacterial structure related to the flagellar type III secretion system, suggesting its involvement in diverse cellular functions.

The paper characterizes the behavior of a single axis holder during FISE acquisition to balance data quality and speed in cryo-electron tomography.

The paper introduces two methods for faster tilt-series acquisition in electron cryotomography, with trade-offs in resolution and speed.
