Elemental sulfur reduction is a key process in anaerobic ecosystems and the global sulfur cycle. Although elemental sulfur serves as a terminal electron acceptor in microbial respiration, the molecula...

Attacks on science and immigrants are destroying America.

Twenty-two strains of mesophilic methanococci were isolated from salt marsh and other intertidal sediments of the southeastern United States. All the …

Here, the authors develop tools to genetically modify Mediterraneibacter gnavus, a human gut bacterium associated with disease, showing that capsular polysaccharides are key for intestinal colonizatio...

In most organisms, ATP synthesis is powered by the proton motive force (pmf) and catalyzed by ATP synthase. While the chemiosmotic theory originall...

Maren Nattermann, Research Group Leader at the Max Planck Institute for Terrestrial Microbiology, on Marjory Stephenson (1885–1948): pioneer of chemical microbiology, whose work on bacterial metabolic...

Structural insights into the assembly of the complex nitrogenase cofactor are scarce. Now, cryo-EM and AlphaFold analyses of NifEN, which converts the precursor (L-cluster) to a mature cofactor (M-clu...

Energy is required for the expression and maintenance of complex traits. In many habitats, however, free energy available to support biosynthesis i...

The MttB superfamily member MtgB catalyzes the methylation of a cognate corrinoid protein with glycine betaine and representatives have been described…
