Electron cryo-tomography reveals a huge conformational change in the secretin domain of the type IV pilus machinery that occurs when the channel opens for pilus extrusion.
A detailed model of the T7 replisome with the precise positions of the helicase and polymerase at the replication fork explains how catalysis by the two enzymes is coordinated.
Small decreases in pH associated with cellular stress conditions unleash a cryptic mode of client binding in a ubiquitously expressed human small heat shock protein that is more effective at delaying client aggregation.

A general framework for gating reveals that inter-head tension is not essential for coordinating kinesin stepping, and that neck-linker length is tuned to enhance processivity and velocity.

Bacterial-encoded covalent adhesion is a new molecular principle in host-microbe interactions and may play a key role in host colonization by a wide range of Gram-positive bacteria.
