Most methanogenic archaea reduce CO2 with H2 to CH4. For the activation of H2, they use
different [NiFe]-hydrogenases, namely energy-converting [NiFe]-hydrogenases …

The continuous degradation and synthesis of prokaryotic mRNAs not only give rise to the
metabolic changes that are required as cells grow and divide but also rapid adaptation to …

Two distinct microbial processes, denitrification and anaerobic ammonium oxidation
(anammox), are responsible for the release of fixed nitrogen as dinitrogen gas (N2) to the …

Recently, a microbial consortium was shown to couple the anaerobic oxidation of methane
to denitrification, predominantly in the form of nitrite reduction to dinitrogen gas. This …

Anaerobic ammonium-oxidizing (anammox) bacteria derive their energy for growth from the
oxidation of ammonium with nitrite as the electron acceptor. N 2, the end product of this …

Thermophiles are referred to as microorganisms with optimal growth temperatures of> 60°
C. Over the past few years, a number of studies have been conducted regarding …

D native electrophoresis is used for the separation of individual proteins, protein complexes,
and supercomplexes. Stable and labile protein–protein interactions can be identified …

Electron transport, or oxidative phosphorylation, is one of the hallmarks of life. To this end,
prokaryotes evolved a vast variety of protein complexes, only a small part of which have …

Nitric oxide is an important molecule in all domains of life with significant biological functions
in both pro-and eukaryotes. Anaerobic ammonium-oxidizing (anammox) bacteria that …

Exosomes emerge as central 3′→ 5′ RNA processing and degradation machineries in
eukaryotes and archaea. We determined crystal structures of two 230 kDa nine subunit …
