Jeff Bezos has forced The Washington Post - the newspaper he owns - to not endorse in a presidential race for the first time 36 years because he’s worried Donald Trump will take away his government contracts. RETWEET if you think @JeffBezos is a disgrace to democracy!

Happy to share our collaborative work with Eric Galburt's lab led by Dr. Ankita Chadda and Dr. Binh Nguyen describing the first structures of dimeric superfamily 1A UvrD-family helicases from M. tuberculosis bound to a DNA junction. biorxiv.org/cgi/content/shor…

These structures show a massive conformational change compared to monomeric UvrD-DNA junction structures. Dimerization occurs via the 2B domains of each subunit which activates the helicase by preventing the inhibitory 2B domain-DNA interactions in the monomer-DNA structure.

The same 2B domain interface occurs in E. coli UvrD dimers suggesting that this is a general interface for SF1A helicases, including Rep and PcrA.

Hetero-dimerization of a wild type and mutant superfamily 1 DNA translocase, neither of which possess DNA helicase activity, results in an active DNA helicase by relieving the auto-inhibition within the monomeric enzyme. doi.org/10.1101/2024.02.20.5…

#NASmember E. Peter Geiduschek was a pioneer of DNA structure and gene expression, and to those who knew him, a "model of rigor and scientific precision as well as of generosity, kindness, and collegiality." Read more in a new memoir: ow.ly/qeRX50QHPAH #MemoirMonday
