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.
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.

A simple, yet elegant method for robust self-assembly of diverse membrane proteins into soluble peptide nanoparticles for their structural and functional analysis in detergent-free solutions.

The intracellular network that distributes iron-sulfur clusters in bacteria is surprisingly 'plug and play' with iron-sulfur enzymes acquired from distantly related species, whereas the intracellular electron transfer network often needs plug adapters to connect with foreign enzymes.

Formation and cell pole-localization of chemotactic signaling-arrays is a coupled process mediated by ParP, which drives localized array-assembly and regulates the localization-dynamics of its network constituents.
The three-dimensional structures of Mycobacterium tuberculosis cytochrome bcc in complex with the antituberculosis agents, Q203 and TB47, explain how these inhibitors suppress activity of the complex.

The molecular mechanism of switching between phosphotransferase- and phosphatase-competent states in histidine-kinases has been uncovered, through direct crystallographic observation of bona fide complexes between a histidine-kinase and its response regulator from Bacillus subtilise.

Structural and functional analyses show how the spliceosomal Prp3 protein concomitantly binds double- and single- stranded regions in U4/U6 di-snRNAs and serves to stabilize the U4/U6•U5 tri-snRNP for splicing.
