Our latest T7SS study is now out in Science Advances! We solved the cryoEM structure of the T7SSb core unit (T7bCU) composed of YukB, YukC, and YukD from Bacillus subtilis, revealing how these components assemble within the secretion machinery. www.science.org/doi/10.1126/...

A ubiquitin-like protein controls assembly of a bacterial type VIIb secretion system

Cryo-EM structure reveals how a ubiquitin-like protein orchestrates assembly of a bacterial weapon system.
