The chloroplast F1Fo ATP synthase is a rotary motor that converts the light-driven proton-motive force into the chemical energy of ATP. The number of c-subunits in its rotor fixes the number of proton...

Bacterial fimbriae are central to adhesion, colonization, and biofilm formation, yet how related fimbriae systems are structurally and mechanically specialized within the same pathogen remains poorly ...

Cyanobacteria are major contributors to global photosynthesis and are intensively studied for sustainable green H2 production. Central to this process is the bidirectional [NiFe]-hydrogenase HoxEFUYH,...

Nature Reviews Molecular Cell Biology - The electron transfer chain in chloroplast thylakoid membranes uses solar energy to produce NADPH and ATP, which power carbon fixation into biomass. This...

The structure and function of the MCR activation complex from Methanococcus maripaludis were revealed, demonstrating its ATP-dependent ability to activate MCR and form methane while uncovering a uniqu...

The Rnf complex is a key respiratory enzyme of anaerobes and nitrogen-fixing bacteria. Here, the authors combine structural, computational, and biochemical experiments to probe the unique redox-couple...

Nature Communications - Symbiont-housing structures are well-studied in multicellular eukaryotes but rarely in unicellular protists. This study shows that low-oxygen-adapted Anaeramoebae have...
