Really looking forward to it. It's a great opportunity to meet friends and make new ones. We are also excited to present our latest structural work on the methyl branch of methanogens. Unpublished and highly exciting!

Emergence of fractal geometries in the evolution of a metabolic enzyme - Nature Citrate synthase from the cyanobacterium Synechococcus elongatus is shown to self-assemble into Sierpiński triangles, a finding that opens up the possibility that other naturally occurring molecular-scale fractals exist.

By any chance??? It is a cyanobacteria right?

Origin of chaperone dependence and assembly complexity in Rubisco biogenesis Molecular chaperones assist with the folding and assembly of protein clients. Consequently, they are essential to diverse cellular functions. In most aerobic photosynthetic organisms such as B-cyanoba...

A new preprint from the lab. I won't do a tweetorial until this is peer reviewed, but I think it's a banger, led by
@JedNzy. It's about Rubisco and what chaperones are really for. He's on the market, get him while you can. www.biorxiv.org/content/10.1...

Oh wow, let's hope with our new discoveries we don't outdate it too fast ;)

Die aller♥️lichsten Glückwünsche🍾🥂auch von uns an Jan Schuller, Wissenschaftler👨🏼‍🔬bei LOEWE-Tree-M & zuvor bereits beim ehem. LOEWE-Zentrum SYNMIKRO, zu seinem #Explorationsstipendium der Boehringer Ingelheim Stiftung!

Structures of dynamic interactors at native proteasomes by PhIX-MS and cryoelectron microscopy Proteasome function depends on a network of transient interactions that remain structurally and functionally unresolved. We developed PhIX-MS (Photo-induced In situ Crosslinking-Mass Spectrometry), a ...

‼️ Exciting new preprint from a close collaboration with Kylie Walters' group. Our study maps the binding sites of key regulators of the proteasome in situ.

This method is an absolute game changer 🔥 when applied to bioenergetic problems. You should have a read. Wait for it 😶‍🌫️ great things are coming!!!

Amazing paper, the best of two worlds- combination of high resolution cryoEM and small proteins - posttranslational Regulation of the core bioenergetic machinery of methanogenesis by a small protein! Well done Tristan and Eva!!👍🥂🥂 @schullerjm.bsky and @Schmitz-Streit lab - possible through @dfg.de

This work is a cornerstone in a long-term effort of the lab to understand the pumps of life. I call it a "Tripple in Bioenergetics" now.

The small protein MtrI blocks the Na+ binding subunit MtrCDE, bascially forming a plug for the channel. This could be important to prevent sodium leakage, when the complex gets damaged by oxygen.

The structure has also something for resolution fans! Such a nice coordinated sodium ion 😅

Tristan could show this by pull-down experiments. Irrespective of the growth condition, the oxygen sensitive behaviour was present.

This is a showcase study how small ORF proteins can regulate a central bioenergetic machinery. MtrI, binds here in a oxygen sensitive manner to the methyltransferase shuttle domain of MtrA.

Proud to present the lab's latest work. The full structure of the sodium translocating methyltransferase (Mtr) bound to a small oxygen-responsive small protein MtrI. Work by Tristan and together with @schmitzstreitslab.bsky.social .

Amazing paper, putting the spotlight on small proteins as modulators of the core bioenergetic machinery of methanogenesis.

Small ORF16 modulates the Mtr complex activity in Methanosarcina mazei Gö1 depending on the molecular hydrogen availability Small open reading frame (small ORF)-encoded proteins, with less than 100 amino acids in length, have attracted increasing attention over the past decade after being largely overlooked due to limitati...

Check out our latest preprint on small proteins with big impact: MtrR fine-tunes energy metabolism in M.mazei by modulating the Mtr complex in response to H₂. Great work of Tim Habenicht + @SPP2002 collegues + @schullerjm.bsky.social - congrats TIM, 2. step to PhD!

Comic. PERSON: It’s weird how, despite being one of the main branches of the tree of life, no archaea species are known to cause disease in humans. PERSON WITH SHORT HAIR: Personally, I think it’s because those gross methane breathers are too weird and incompetent to figure out how to hurt us even if they wanted to. [from small point under microscope on desk]: *Hey!* [caption] Bad news: After overhearing a conversation in our lab, Archaea has finally started harming humans.

This is so cool 😎 congratulations 🎉 amazing work.

Does he believe in 0.143, 0.3 or 0.5 as the correct cutoff?

What a nice story and an engaging video presentation. Congratulations 👏

Two scientists, a woman and a man, wearing safety goggles and lab coats, examine a robotic device. Overlaid text reads "Choose Europe – Freedom to explore, research and innovate. Discover how" with the European Union flag.

The EU flag is shown with a headline "Europe offers:" followed by a list: Stable funding and careers, Academic freedom and scientific excellence, High quality of life (healthcare, education, pensions), and Collaboration beyond borders.

Two young women smile while looking at a tablet, surrounded by EU stars. Text reads: "Choose Europe – €500 million for 2025–2027 to make Europe a magnet for researchers."

Here is one big reason to choose Europe to advance with your research career:
