Novel nitrite reductase domain structure suggests a chimeric denitrification repertoire in the phylum Chloroflexi
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
