The hinge bypass gate paper is finally out! doi.org/10.1038/s414...

We show how loop-extruding SMC complexes can maintain DNA entrapment while bypassing obstacles on DNA — including transcription machinery & potentially other SMCs.

A lucky convergence of 3 projects lead to the initial discovery!
The SMC Hinge is a Selective Gate for Obstacle Bypass - Nature Communications
SMC complexes are ring-shaped motors that fold DNA by extruding loops, but how they navigate large DNA obstacles is unclear. Here, Liu et al., show that SMC complexes bypass obstacles by threading obs...

Brand new preprint from my lab, showing that TnpB, the ancestor of Cas12, acts as a gene drive in plasmids! And it turns out in conjugative plasmids that it acts as a primitive anti-self defense system, providing a potential link between its transposon effect and becoming CRISPR!
What is the best strategy to win any contest?

Eliminate your opponents of course.

Recently, my friend @fernpizza.bsky.social showed how plasmids compete intracellularly (check out his paper published in Science today!). With @baym.lol, we now know they can fight.
