New article online: Modulation of archaeal hypernucleosome structure and stability by Mg2+
In this work, we dissect the effects of Mg2+ on hypernucleosomes formed by the canonical histones from M. fervidus (HMfA and HMfB) and T. kodakarensis (HTkA and HTkB).

Henipaviruses, like Nipah and Hendra, package their genomes inside helical shells built by thousands of nucleoproteins. These nucleocapsids are essential to protect the viral RNA, but how do they ever let the polymerase in to read the sequence?

How does catalysis emerge from non-catalytic domains?
In our new paper, we show that catalytic activity can arise without conserved active-site residues — through multimerization and electrostatic features instead.
A striking case of catalysis evolving from binding.

@claudele.bsky.social et al. studied the fundamental question of how enzymatic activity emerges by focusing on type B dihydrofolate reductases, suggesting DfrB domains evolved rudimentary catalysis from a binding capacity.
