Antivitamins mimicking vitamin B12 can trick bacterial riboswitches into turning down gene expression. This means antivitamins not only inhibit B12-dependent processes but also affect their regulation. 2/2

Our recent work on Actinobacterial G protein system is live on bioRxiv! These regulatory systems are conserved in Actinomycetota and are involved in secondary metabolism, phage defense, and cellular development. Check out the preprint here 👇:

Taga lab (past and present) will be at #ASMMicrobe2025! Swing by our posters to learn more about corrinoid producers in Archaea and more! Poster details are included in this thread. @asm.org #ASMMicrobe #MicroSky #ASMMicrobe25 #Microbe2025
What a great time with Pete Greenberg, @tagalab.bsky.social, @cwhitch.bsky.social, @laahrs.bsky.social, and Jeff Boyd in Dresden
+ learning about the history of quorum sensing research, the 2Ms, Matt and Marvin, BB medium, and many more stories

Congratulations to our RaMP scholar, Farrah, for a great talk at the Bay Area RaMP in Microbiome Sciences! We are so proud of you!
They are not only required by humans, but also by nearly all bacteria. However, only a subset of bacteria can synthesize them, making them important shared nutrients. 3/4
Check out our new paper led by lab member Kenny Mok! We highlight that understanding individual cobamide preferences of bacteria is necessary to understand the critical function of these vitamins in microbial communities. 1/4 journals.asm.org/doi/full/10....
Here, we tested a number of model bacteria and compared the results to previous studies. We found that cobamide preferences and requirements vary broadly across bacteria, as well as in cobamide-dependent pathways within the same organism. 4/4
What are cobamides and why are they important? Cobamides, with nearly twenty different forms found naturally, are the vitamin B12 family of molecules. 2/4
Microbes display broad diversity in cobamide preferences
