Membrane binding controls the ATPase cycle and localization of MinD in Bacillus subtilis
Dynamic relocalization of MinD in Bacillus subtilis arises from membrane binding of monomers and dimers with membrane-triggered ATP hydrolysis, suggesting MinE-like activators are unnecessary for Min ...

Delighted to see the main work from my PhD finally published in
@mbio.bsky.social
! It all started with the observation that deleting the cutRS two-component system in S. venezuelae caused this amazing explorer phenotype in the presence of glucose. But what was going on?! (1/n)

A shared alarmone–GTP switch controls persister formation in bacteria - Nature Microbiology
Alarmone synthesis depletes GTP levels leading to a GTP-dependent switch that controls triggered, spontaneous and antibiotic-induced persister formation in Bacillus subtilis.

Fellow bacterial cell biologists, message me if you use
@thermofishersci.bsky.social
Gene Frames for microscopy! Thermo are planning to discontinue these in September but have indicated they will look into this further. If I make list of labs using them Thermo might not kill the product Please RT🔬🦠
