Cyanobacterial RNA-binding protein Asl3888 is ribosome-associated and involved in C/N metabolism. It is encoded in almost all cyanobacteria, green, red, and brown algae, diatoms, cryptomonads, and pelagophytes.

I can't believe what I've just watched.

A Jewish lawyer wearing a Star of David was arrested after the police alleged the symbol had "antagonised" pro-Palestine protesters.

He was handcuffed and detained by police for almost TEN hours. DISGUSTING!

Shame on you @metpoliceuk.

From the humblest of beginnings (i.e. a pile of dry cow dung) over 80 years ago, the Gram-negative bacterium Myxococcus xanthus has emerged as a premier model system for studying diverse fields of bacteriology journals.asm.org/doi/full/10.11…

Very happy to share that a large part of my thesis work is out today: B. subtilis uses the second messenger c-di-AMP to modulate its turgor pressure in response to the state of its cell envelope.  nature.com/articles/s4156…

In the architecture of the outer membrane complex PelBC for Pel export, the essential periplasmic ring of twelve PelC lipoproteins is mounted on top of the PelB β-barrel

In Bacillus subtilis, c-di-AMP levels are modulated by the cyclase regulator CdaR in response to cell wall defects. Great work by @apbrogan.bsky.social et al.
