The overall energy conversion efficiency is calculated for a bacterial vesicle that harvests solar energy for ATP production on the basis of an atomic-detail structural model.

Bacterial cytoplasmic chemoreceptors assemble into a sandwich of two hexagonally packed arrays.

Cryo-EM structures reveal how the peptidisc scaffold can adapt to different membrane proteins, establishing it as a universal membrane mimetic to stabilize membrane proteins in solution.

Under starvation conditions, anti-carD antisense RNA and Clp protease work together to decrease the CarD level to mediate the adaptation and survival of mycobacterial cells.

A novel B12 containing photoreceptor is synthesized as two different isoforms that interact with the same transcription factor, with one isoform directing activation and the other promoting repression of photosystem synthesis.

Revisiting limitations in time-resolved X-ray free-electron laser structures of the bacterial photosynthetic reaction center uncovers their irrelevance to proposed structural changes in electron transfer dynamics.

Genetic, biochemical, and cell biological approaches reveal a new form of contact-dependent inhibition in bacteria involving bacteriocin-like proteins that aggregate on the surface of cells.

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.

Investigations of the reaction center (RC)-light harvesting (LH) complex from an ancient chlorosome-less anoxygenic phototroph Roseiflexus castenholzii reveal the structural basis by which carotenoids assembly regulates the architecture and quinone exchange of bacterial RC-LH complex.

SAK1, a novel cytoplasmic phosphoprotein, is a key intermediate component of the retrograde signaling pathway controlling nuclear gene expression during acclimation of Chlamydomonas cells to singlet oxygen stress.
