Translation for last year PhD students: You want to watch the ARC webpage tomorrow to see who will be looking for postdocs in 2026

Structural and mechanistic insights into translation initiation on the enterovirus Type 1 IRES Enteroviruses are a widespread and diverse set of pathogens responsible for over ~1 billion human infections annually. Upon cell entry, translation of the virus genome is mediated by an internal ribos...

Enteroviruses cause over a billion infections each year, but the details of how their genomes capture host ribosomes have remained elusive. I'm pleased to share a new preprint from Miguel in our group, providing some new insights into this problem:

A new paradigm for outer membrane protein biogenesis in the Bacteroidota - Nature Structural and biochemical studies of the β-barrel-assembly machinery from Flavobacterium johnsoniae reveal a subunit composition and assembly that are distinct from those of the canonical Escherichia coli complex.

A Protein Antibiotic Inhibits the BAM Complex to Kill Without Cell Entry Many antibiotics are ineffective against Gram-negative pathogens such as Pseudomonas aeruginosa because they cannot penetrate the bacterial outer membrane. Here, we show that protein antibiotics calle...

Check out our preprint in which we determine how a class of potent protein antibiotics specifically kill P. aeruginosa without a need to enter the cell.

This is an amazing paper led by the Grinter lab on bacterial protein antibiotics called pyocins and the mechanism by which they inhibit the BAM outer membrane complex. @rhyswg.bsky.social, @knottrna.bsky.social, @debnathghosal.bsky.social, @doylemt1.bsky.social, @fabianmunder.bsky.social

This work was a huge team effort led by the extremely talented @fabianmunder.bsky.social.

Many thanks and congratulations to everyone who contributed! Too many to thank here but check out the author list.

The outer membrane of Gram-negative bacteria blocks many antibiotics. Our latest work reveals that L-type pyocins bypass this barrier by inactivating the BAM complex, killing Pseudomonas aeruginosa without entering the cell, providing a new blueprint for beating antibiotic resistance.

Code to complex: AI-driven de novo binder design In this review, Fox et al. discuss how artificial intelligence has transformed our ability to design new-to-nature proteins that bind target proteins with high affinity and specificity. The authors de...

Next-level hydrogenase fuel cell just dropped, congrats @rhyswg.bsky.social and @greening.bsky.social et al.!

Nanoengineered bioanode with oxygen-insensitive hydrogenase for sustainable energy harvesting from atmospheric hydrogen and waste gases Enzymatic biofuel cells (EBFCs) utilizing hydrogenases to oxidize hydrogen offer a sustainable approach to energy conservation. However, the oxygen se…

1/3 Electricity from air! In the top journal Nano Energy today, we report the first fuel cell that makes power from air alone. We achieved this by using the enzyme Huc to oxidize ambient hydrogen. This results in a continuous low-level power from air and higher outputs with industrial waste gases.

In this system, bacteria detect phage infection through a sensor protein (YjbH) and respond by severing the infected part of the cell via aberrant division. The rest of the cell survives and continues growing happily, essentially, bacterial autotomy!

📣 New paper alert! Just out in Cell Reports! pubmed.ncbi.nlm.nih.gov/40644298/
Thrilled to share that we have discovered a brand-new anti-phage defense system! Bacteria have evolved various defense strategies (CRISPR etc) to counter phage attacks. We found a new one - fascinating and dramatic

Excellent nanomolar peptide design success rates with BindCraft!

I am super excited to announce that I will be starting my lab at the Department of Pharmacology of the University of Zurich in Switzerland next year!

Did you know that some bacteria can generate ATP, the energy currency of life, literally out of thin air? 🌬⚡️

In PNAS today, we show how bacteria can do this using just three enzymes. Honoured to contribute to this study with Christoph von Ballmoos, Chris Greening and Gregory Cook

Our article showing energy production from air alone is in PNAS today. This paper provides an ultimate biochemical proof that microbes can survive simply by 'making' energy from air (making two ATP per molecule atmospheric H2 consumed) and has biotech applications. www.pnas.org/doi/10.1073/...
