DNA gyrase, a regulator of bacterial genomes topology, is shown to undergo rearrangements while functioning on DNA in vitro, with important potential consequences for gyrase-targeted antibiotics activity and bacterial evolution.
A combined theoretical and experimental study revealed the mechanistic and structural basis of mutational effects on allostery and provided insights into the intrinsic connection of intra- and inter-domain properties.

The mutation of Lys125 in connexin26 to glutamate, a carbamylation mimetic, pushes the equilibrium of the gap junction channel seen in cryo-EM towards a more closed conformation.

Enteric bacteria associated with bloodstream infections are attracted to human serum through L-serine and the chemoreceptor Tsr, and in an enterohemorrhagic lesion model use chemotaxis to invade damaged vasculature.
Advanced cryo-EM approaches reveal surprising insights into the molecular structure that allows nascent proteins to be inserted into the membrane of the endoplasmic reticulum.

Biochemical and structural analyses unravel how two RIG-I-like helicases function together to promote antiviral defense and illustrates the diverse ways innate immunity evolved.

A comprehensive allosteric model describes how inhibitors can activate rather than inhibit a target kinase by selectively driving formation of kinase dimers with one inhibited and one activated subunit.
