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.

Evolution tunes functional sub-state interconversion to boost enzyme function Enzymes do not operate as static structures, but continuously fluctuate between different conformations. Enzymes therefore dynamically sample conformations with varying catalytic activity. However, it...

🚨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 🧬.

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

APC24-7, a covalent combination of boronic acid and chelator moieties, restores β-lactam efficiency against metallo-β-lactamase-producers | mSphere The ability of bacteria such as Klebsiella pneumoniae and Escherichia coli to circumvent antimicrobial chemotherapy has become a global public health crisis. The high prevalence of β-lactamase enzymes...

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.

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!

Functional sub-states link conformational landscapes and protein evolution The intrinsic conformational flexibility of proteins creates structural heterogeneity, giving rise to conformational ensembles within the energy lands…

🔄 #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.

Transparent peer review to be extended to all of Nature’s research papers From today, all new submissions to Nature that are published will be accompanied by referees’ reports and author responses — to illuminate the process of producing rigorous science.

Nature goes full open review!

I have complicated feelings about how and when this was achieved!

And they should be apparent to you after even a moment’s thought about the subtext here!

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

Are you interested in how #epistasis shapes the AMR evolution?

We showed that epistasis can be caused by independently modulating substrate binding and the chemical step ultimately changing the rate-limiting step in the catalytic cycle. @NatureCatalysis
