Abstract:Denitrification plays a central role in the global nitrogen cycle,
reducing and removing nitrogen from marine and terrestrial ecosystems.
The flux of nitrogen species through this pathway has a widespread
impact, affecting ecological carrying capacity, agriculture, and
climate. Nitrite reductase (Nir) and nitric oxide reductase (NOR) are
the two central enzymes in this pathway. Here we present a previously
unreported Nir domain architecture in members of Phylum Chloroflexi.
