Inside the acidic vacuole, expression, DNA binding and DNA binding affinity of the Salmonella regulator SsrB is stimulated by acid pH.

Cryo-EM structures of the AAA+ ClpXP protease bound to an ssrA degron reveal the mechanism of substrate recognition and show how the machine transitions from recognition to translocation and unfolding.

A response regulator acquired via lateral gene transfer has rewired an ancestral genetic circuitry and regulates alternative pathogenic lifestyles.

Individual SSB-ssDNA complexes undergo reversible condensation and de-condensation that is modulated by RecOR during recombination.

RecO efficiently displaces SSB from ssDNA without consuming ATPs using its two DNA-binding sites, even though SSB binds to ssDNA approximately 300 times more strongly than RecO does.

Clear guidelines and open-source software resources are provided for the stop-signal task, in order to streamline the use of this important tool, and to thereby increase its validity and reliability.

Caenorhabditis elegans require a GPCR to recognize and rapidly escape from toxin-producing Streptomyces at their head or tail.

Single-molecule force and fluorescence spectroscopy reveal the structural states and dynamics of E. coli single-stranded DNA binding proteins and the energy landscape of the nucleo–protein complex.

A structural investigation reveals details of the mechanism by which the nuclease RecJ processes DNA ends to repair double strand breaks.

The brown planthopper has evolved a highly adaptive oviposition strategy by exploiting caterpillar-induced plant volatiles that provide safe havens for its offspring.
