A wide range of Bacteria and Archaea sense cellular 2-oxoglutarate (2OG) as an indicator of
nitrogen limitation. 2OG sensor proteins are varied, but most of those studied belong to the …

The nitrogen cycle (N-cycle) in the biosphere, mainly driven by prokaryotes, involves
different reductive or oxidative reactions used either for assimilatory purposes or in …

In recent years, our understanding of biological nitrogen fixation has been bolstered by a
diverse array of scientific techniques. Still, the origin and extant distribution of nitrogen …

Background Renewable energy production is currently a major issue worldwide. Biogas is a
promising renewable energy carrier as the technology of its production combines the …

Interactions between microbial species are sometimes mediated by the exchange of small
molecules, secreted by one species and metabolized by another. Both one-way …

The PII family of signal transduction proteins are among the most widely distributed signal
proteins in the bacterial world. First identified in 1969 as a component of the glutamine …

▪ Abstract Lateral gene transfer (LGT) is now known to be a major force in the evolution of
prokaryotic genomes. To date, most analyses have focused on either (a) verifying …

Most biological nitrogen fixation is catalyzed by molybdenum-dependent nitrogenase, an
enzyme complex comprising two component proteins that contains three different …

The methanogenic Archaea bring a broadened perspective to the field of nitrogen fixation.
Biochemical and genetic studies show that nitrogen fixation in Archaea is evolutionarily …

The genome sequence of the genetically tractable, mesophilic, hydrogenotrophic
methanogen Methanococcus maripaludis contains 1,722 protein-coding genes in a single …
