The architecture of the bacterial cytokinetic ring in cells and in artificial liposome reconstitutions has been described using electron microscopy, leading to a mechanism of constriction.

Glycosylation of flagellins with pseudaminic acid in the bacterial cytoplasm governed by an unknown type of modular glycosyltransferase harboring an N-terminal substrate binding domain and a C-terminal glycosyltransferase domain.

Common ancestries, activities and structural determinants of a modular (bi-)polarization control system encoded in free-living and obligate intracellular α-proteobacteria, including the rickettsial pathogens, are described.

A multi-layered and conserved cell cycle mechanism prevents capsulation, long known as a bacterial virulence determinant, in G1-phase and concurrently licenses bacteriophage-mediated genetic exchange prior to entry into S-phase.

Live-cell imaging shows that replication-independent specialized polymerase action is a consequence of lesion processing via NER and impacts cellular survival under stress outside replicative phases of the cell cycle.
The prokaryotic actin homologue MreB forms antiparallel double filaments in vitro and in vivo, an architecture that is unprecedented among the actin family of proteins.
Genome dilution limits cell growth by modulating the activities, rather than the concentrations, of RNA polymerases and ribosomes, and is accompanied by changes in proteome composition.
