Interested in #archaea, #methane, #cell-envelopes?
New paper out @nature.com !
We discovered an enzyme that specifically cleaves the cell wall of methanogens, revealing a new chemical structure of archaeal peptidoglycan, 50 yrs after its first description

Diverse S-layer anchoring mechanisms create an epiplasmic space in prokaryotic cell envelopes.

The S-layer is the most widespread and fundamental component of archaeal cell envelopes and may represent one of the earliest and most fundamental cell wall polymers found in microorganisms

When systems fail us it’s community that saves us.

Before there were corporate sponsorships there were friends passing envelopes under cell doors, commissary money pooled together, or a ride to a court date given without question.

That’s the heart of mutual aid: solidarity keeps our people alive.

The last time we went through this - 1995’s Nixon stamps - a brilliant entrepreneur developed the appropriate envelopes (I know because I bought a bunch). I’m sure someone can come up with something as good, maybe Baldwin owning Buckley.

The @henrikstrahl.bsky.social group focuses on bacterial cell envelopes and envelope-targeting antibiotics.
Using cell biology, high-end fluorescence microscopy, genetics, and biochemistry, they study the function, biosynthesis and organisation of bacterial cell membranes.

He better make 100 back ups, put them in bank safety deposit boxes, and others in envelopes marked for every News station, hire a Security Team and move out of his home. They will be coming for you.

The unique #CellEnvelope of #corynebacteria: @tbharat-lab.bsky.social &co map the C. glutamicum cell surface, revealing a patchy S-layer & specific assembly of the PS2 protein, thereby informing our understanding of cell envelopes that contain #MycolicAcids @plosbiology.org 🧪 plos.io/3Y6JNgw
Left: The atomic model of the PS2 lattice is shown in top and side views. PS2 hexamers are repeated in the 2D sheet with a lattice constant of 176 Å. Each PS2 monomer is colored and labeled separately within the hexamer, which repeats throughout the lattice (with pore dimensions highlighted). The side view of the lattice shows the smooth surface facing the extracellular space and rough surface with coiled-coil segments protruding towards the MM. Top right: Interactions at the hexameric and trimeric interfaces are stabilized by both hydrophilic and hydrophobic residues. Bottom right: A cell envelope tomogram was used to overlay the cryo-EM structure of the S-layer onto the in situ S-layer tomographic density. A single slice of the tomogram is shown, with the overlayed PS2 S-layer lattice in green and the tomogram in grayscale. The S-layer (surface layer), MM (mycomembrane), IM (inner membrane), and Cytosol are labeled.

captchas get more baffling by the day but I can't decide whether it's because they actually make less sense or because the pictures are so bad that my elderly eyes just can't tell what I'm looking at anymore.

The excitement continues! Check out my latest preprint examining how phages have adapted to lyse different bacterial envelopes. I found a lysis gene (lysZ) that is conserved in phages that infect corynebacteria mycobacteria, and other actinos.

Bacteriophages target membrane-anchored glycopolymers to promote host cell lysis and progeny release
Most bacteriophages lyse their host cell to release progeny virions. Double-stranded DNA phages typically promote host lysis using a holin-endolysin system. Holins form pores in the cytoplasmic membra...

Archaeal PG structure was characterized in the late 70s by pioneering work of Kandler and König on cell envelopes, which supported Woese’s proposal of Archaea as a third domain of life. It showed clear differences with bacterial PG, making it resistant to well-known enzymes (remember lysozyme?) 3/9

I've had the Winged Star for less than 10 minutes at the Gamescom Kirby booth and still miss it #kirby #kirbyairriders #I'mnotpaying500bucksevenifitsformyboyo #butthegamewasreallyfun
fanart of kirby air riders. It's mostly cell shaded, with a few gradients as well. Kirby is in the center, holding onto the Winged Star with his left hand and looking to the left with a happy expression. Behind the Winged Star, stars are coming out its engines and trailing behind in a curve that becomes thicker and envelopes the entire down right corner of the drawing. The background where stars are is dark blue and resembles space, getting more yellow near the engines, while everything else is a bright day sky. The sun can be seen shining behind Kirby, giving him and the Winged Star a halo effect. A ray of sunshine is reflecting off the tip of the Winged Star, causing a lens flare. A few clouds are in the sky, going in circles around the sun (and kirby by extension). The entire drawing has a blur effect applied near its edges and on things far away from Kirby.
