Das größte bekannte #Enzym? Ein Team um @sophia-pa.bsky.social und @schullerjm.bsky.social vom @synmikro.bsky.social hat einen überzeugenden Kandidaten: einen katalytisch aktiven 8 MDa-Superkomplex aus einem Methan-produzierenden Archaeon … Mehr dazu: 👉https://www.laborjournal.de/editorials/3533.php

Some bacteria do not live as individuals. They build multicellular filaments and connect neighboring cells through tiny cell-cell junctions. Cyanobacteria are among the most beautiful examples 😍 In our new paper, we reveal first molecuar insights on the cyanobacterial septal junction architecture 🧵

Awesome work to determine the structure of a freakin 8MDa enzyme complex with over 600 FeS clusters! Sophia won the poster prize at the recent GRC C1 👏 www.nature.com/articles/s41...

Architecture of the 8 MDa Hdr–Vhu–Fwd super-assembly in class I methanogens - NatureThe structure of the Hdr–Vhu–Fwd super-assembly reveals a lineage-specific and modular 8 MDa complex with the ability to adapt to diverse anaerobic niches.www.nature.com

Huge discovery from Marburg: Prof. Schuller (@synmikro.bsky.social),doctoral stud. @sophia-pa.bsky.social+colleagues have resolved1️⃣of the🧬🔬largest enzymes. Published in Nature, the study shows how methanogenic archaea generate energy under extreme conditions, offering🆕insights into the🌎carbon cycle.

Excited to share my paper! 🥳 Today in #Nature we reveal an 8 MDa Hdr electron bifurcating super-assembly in class I methanogens that couples the first and last steps of hydrogenotrophic methanogenesis. A lineage-specific adaptation to anaerobic niches. www.nature.com/articles/s41...

1/ Happy to share our preprint! The Mtr complex catalyses the second-to-last step of the methanogenesis and is an essential bioenergetic machine in most methanogenic archaea. Anaerobic cryo-EM of Mtr reveals a nitrogenase-like metallocluster bound at its active site! www.biorxiv.org/content/10.6...

Super excited to launch this search for a new endowed professor at the @biozentrum.unibas.ch! Join us to build a research cluster in Climate Biophysics! 🌍🌊🌾🔬🧪 This is a unique opportunity to create a community in Basel🇨🇭working together on this timely topic! ⏳🌡️ Questions? Please reach out! 👩‍🔬👨‍🔬

Crazy biochemistry is the norm for @schullerjm.bsky.social, but here I wanna say I have witnessed up close the amazing effort from @tomaspascoa.bsky.social and @tamb-o.bsky.social to chase the BCRII complex in situ 🤩 Big congrats to Lena Appel and @rnfr2d2.bsky.social for the cryoEM structure too 👏🏽

Across scales from cells🦠 to atoms⚛️ – We reveal how anaerobic #bacteria break down very stable aromatic compounds found e.g. in oil spills 🛢️ #Bioremediation #TeamTomo 🧪 🧶🧬 🔬 Awesome collab with Lena, Matthias, @schullerjm.bsky.social @rnfr2d2.bsky.social @tomaspascoa.bsky.social @tamb-o.bsky.social

Thanks for the fun collaboration into this fascinating “oil eating” biomachine. I learned a lot! 🧪 #TeamTomo

Amazing paper. A megadalton enzyme complex that: - combines both electron bifurcation AND confurcation steps - has a new type of iron-sulfur cluster - a new kind of weird electron transfer path - super charges electrons to reduce aromatic rings - also powers respiration 😳

How do “LEGO-like” electron-bifurcating modules combine to drive degradation in BTEX-contaminated ecosystems? Check out our latest preprint, where we use cryo-EM and cryo-ET to reveal how the 1 MDa BCRII complex powers extremely endergonic aromatic ring reduction. www.biorxiv.org/content/10.6...

1/ Excited to share our preprint! 🥳 Degradation of aromatic compounds, including BTEX pollutants, requires highly endergonic aromatic ring reduction. Using #cryoEM and in situ #cryoET, we show how BCRII couples electron bifurcation modules in one giant redox machine www.biorxiv.org/content/10.6...

I will probably be hiring either a PhD or a Postdoc in the near future. If you are interested in deep biochemical history or molecular mechanisms of evolution please get in touch.

Carbonic anhydrase catalyses the interconversion of CO2 and HCO3- and helps increasing the net-CO2 concentration inside cells. Why? CO2-reducing enzymes like RuBisCO are notoriously slow and ineffective. However, import of HCO3- is typically coupled to ATP consumption...

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...

Origin of chaperone dependence and assembly complexity in Rubisco biogenesisMolecular 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...www.biorxiv.org
