    A low Smc flux avoids collisions and facilitates chromosome organization in Bacillus subtilis

    Anna Anchimiuk et al.
    Bacterial chromosome folding by DNA loop extrusion is here shown to rely on avoidance of SMC collisions by low SMC abundance, clustering of loading sites, efficient translocation, and rare unloading.

    Genome rearrangements and pervasive meiotic drive cause hybrid infertility in fission yeast

    Sarah E Zanders et al.
    Rapid acquisition of chromosome rearrangements, together with independently acting transmission distorter alleles on each chromosome, drive near complete sterility in fission yeast hybrids.

    Visualization and functional dissection of coaxial paired SpoIIIE channels across the sporulation septum

    Jae Yen Shin et al.
    SpoIIIE forms a protein channel that spans the two lipid bilayers of the septum and mediates chromosome translocation and reversible membrane fission during Bacilus subtilis sporulation.

    Mechanochemical coupling and bi-phasic force-velocity dependence in the ultra-fast ring ATPase SpoIIIE

    Ninning Liu et al.
    Probing the DNA motor SpoIIIE at the single-molecule level has revealed its force-generating step, rich translocation dynamics during motor operation and a novel, bi-phasic mechanical response to opposing force.
