Long day, but rewarded with this stunning cycle home
Microbes that have the greatest genomic potential for secondary metabolism tend to be multicellular. Here, we show that signatures of ancestral BGC expansions within 3 bacterial phyla and 2 fungal lineages coincide with origins of complex multicellularity [1/12] 🧵 www.nature.com/articles/s41...
Complex multicellularity is linked with expanded specialized metabolite production in microorganisms - Nature Microbiology
The evolutionary emergence of complex multicellularity in bacteria and fungi, such as the ability for mycelial growth, is strongly associated with increased genomic carriage of biosynthetic machinery ...

This has been such a fun collaboration and a great example of team science
New paper in collaboration with @proftracypalmer.bsky.social, @lislowe.bsky.social and many more. We show that mycobacteria produce Type VII secreted anti-bacterial protein toxins. Excited to explore this new area of mycobacterial biology. www.nature.com/articles/s41...

Improved fractionation strategies can identify antibiotics with previously unseen scaffolds and mechanisms, exemplified by manikomycin from Streptomyces rimosus, which acts by targeting the E-site of the bacterial large ribosomal subunit.

Our study on Bacteroides iron piracy is now out in @pnas.org. We show how surface-exposed lipoproteins bind xenosiderophores with different iron-chelating chemistries and propose a mechanism for xenosiderophore import across the outer membrane. Lots of structures (mostly X-ray this time)!
