In situ cryo-electron tomography unveils the molecular sociology of a developing sporangium in Bacillus subtilis, revealing critical information about cell wall remodeling and membrane migration in bacteria.
An atypical subtilase protein, resulting from an alternative splicing event, mediates retention of the defence related-transcription factor MYB30 at endosomal vesicles, thus repressing Arabidopsis antibacterial immunity.
Imaging experiments and simulations reveal that the biophysical mechanism for force generation needed to engulf a forespore is based on coordinated cell wall synthesis and degradation.
The Smc–ScpAB complex-a prokaryotic ancestor of cohesin, condensin and Smc5/6-loads onto the bacterial chromosome by employing ATP hydrolysis to capture DNA fibers within its tripartite ring.
MreB filaments bind, orient, and move along the direction of greatest membrane curvature, thus orienting the insertion of new glycan strands around the cell circumference in a manner that may help establish and maintain rod shape.
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.
Structures of active and inactive conformations of a PP2C family phosphatase reveal a conserved switch that controls enzymatic activity and point to an unexpected relationship between phosphatases and proteasomal proteases.
