Diversity of electron-bifurcating CO2-fixing supercomplexes in methanogens

In the hydrogenotrophic methanogenic pathway, formylmethanofuran dehydrogenase (Fmd) reduces and fixes CO2, driven by low-potential electrons provided by electron-bifurcating heterodisulfide reductase (Hdr) complexed with electron-donating proteins such as Mvh hydrogenase. Here, we report the structure of a C2-symmetri...

Structural basis of sulfide production in dissimilatory sulfur metabolism

The membrane-bound DsrMK(JOP) complex is central to dissimilatory sulfur metabolism, including in sulfate-reducing microbes (SRM), a group that plays important roles in shaping planetary and human health. Despite this global importance, the mechanism of sulfide production and its links to energy conservation remain unc...
