It was great to play a part in this study, using all of the work on alphaproteobacterial GTAs to help inform and identify key tell-tale patterns of GTAs in the human gut microbiome. I'm sure there will be many great followup studies on these fascinating particles.

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.
