🦠 #Collateralsensitivity, when resistance to one antibiotic creates vulnerability to another, offers a route to fight #AMR. We followed the evolution of #β-lactamase OXA-48 and show mutations can both create AND mitigate these trade-offs. 💊 doi.org/10.1016/j.jm...

We studied the causes of #collateralsensitivity from a single enzyme perspective using and how stable such #tradeoffs are during #coselection. In short, resistance evolution can cause strong but migigatable trade-offs. Preproof is now available on @JMB: www.sciencedirect.com/science/arti...

Sometimes, adaptation to one #antibiotics can make bacteria more vulnerable to other drugs. #CollateralSensitivity. 💡 By following the evolution of a β-lactamase, we uncovered how mutations can both create and mitigate such collateral sensitivity networks. www.biorxiv.org/content/10.6...

🚨PREPRINT🚨 Enzyme function does not rely only on static structure 🧩, but also on the rate at which functional sub-states interconvert ⏱️, making this interconversion subject to natural selection 🧬. #OXA-48 #ceftazidime #enzymeevolution www.biorxiv.org/content/10.6...

Living in the Arctic 🥶 means Christmas comes early 🎁🥳 10 MNOK (≈1 MUSD) Early Career Investigator grant from the Research Council of Norway to work with the fabulous @bunzela.bsky.social (Max Planck Institute) on uncovering the molecular mechanisms of antibiotic resistance. #AMR #beta-lactamases

Interested in #β-lactamase inhibitors? 🧪 Our new #mSphere paper shows how a covalent boronic-acid + chelator fusion ⚗️ can restore β-lactam susceptibility in metallo-β-lactamase producers, even in variants that are difficult to inhibit with #taniborbactam. journals.asm.org/doi/full/10....

Is it too early for a year review? 🤔 Research stays at ETH Zürich with Adrian Bunzel and at UBC Vancouver with Nobu 🤓. Now I’m moving labs to start as Associate Professor at UiT, which means organising freezer contents 📦. Two β-lactamase evolution preprints coming soon 🧬. Stay tuned!

🔄 #Enzymes can adopt multiple #conformations. ⚡ Some of these act as functional sub-states. 📚 We summarised recent studies, the methods used to uncover these hidden states, and the challenges ahead in linking them to #proteinevolution. www.sciencedirect.com/science/arti...

I highly recommend this conference, i thoroughly enjoyed the 2022 meeting 👇🏻
