A single phage enzyme can target thousands of bacterial proteins, shutting down host defences, a new EMBL study shows. The study provides novel insights into bacteria-virus interactions and opens up new possibilities for bioengineering for phage therapy. www.embl.org/news/science...

Excited to share our paper with @savitski-lab.bsky.social, led by @tarabartolec.bsky.social, Karin Mitosch & Clément Potel, out now in @nature.com. We show that T7 phage broadly disables bacterial defenses using a unique ‘loose cannon’ protein kinase. www.nature.com/articles/s41...

1/5 How much phosphorylation can a single kinase deposit? In our new study with @typaslab.bsky.social out in @nature.com, phage T7's kinase (T7K) modifies almost all the E. coli proteome + more densely than all ~500 kinases do our own proteomes 🤯 www.nature.com/articles/s41...

Some small molecules modulate protein condensation in cells, but how? Our latest work shows a possible mechanism of action of the small molecule lipoamide. This molecule prevents condensation of stress granules whose components are found as protein aggregates in ALS. www.nature.com/articles/s41...
