1/5 Happy by a recent biorxiv pre-print about DARNA (PD-T7-3) anti-phage defense system. This system is activated by binding to ssDNA, presented by phage SSB, to cleave tRNA in the anti-codon loop. www.biorxiv.org/content/10.6...

Understanding how enzymes work: the journey to ensemble–function studies febs.onlinelibrary.wiley.com/doi/10.1111/... This is an exceptionally well written review on how enzymes work. Rather than the structure-function relationship, Herschlag & Du analyse the ensemble-function relationship

1/6) Hot off the press @natsmb.nature.com 🔥! Jasnauskaite et al. reveal how the minimal bacterial retron Eco2 defends against #phage 🛡️. Phage nucleases trigger Eco2, which cuts RNA, shuts down protein production and stops phage replication 🦠🚫. #phagesky #immunity #microbiology #cryo-em rdcu.be/e4AyH

New online: Structure and mechanism of antiphage retron Eco2

Our work is published today: ‘Oxygen metabolism in descendants of the archaeal-eukaryotic ancestor’. This was a huge effort lead by @katyappler.bsky.social. Extremely grateful to have been a part of this amazing project! 😊🦠🧬 Links: www.nature.com/articles/s41... www.nature.com/articles/s41...

Check out our latest paper on mirusviruses, one of the most remarkable new groups of protist viruses - extremely diverse, carry lots of spliceosomal introns (including new homing introns) and are at the evolutionary crossroads between tailed phages and herpesviruses! www.nature.com/articles/s41...

Officially out!

Now out in Science! Cyclin-dependent kinases (CDKs) are key regulators of the cell cycle. In @vcushing.bsky.social's magnum opus, we use #cryoEM to figure out how the CDK-activating kinase recognises CDKs to fully activate them - a key step in cell cycle control. www.science.org/doi/10.1126/...
