Nitrate reduction to ammonia via nitrite occurs widely as an anabolic process through which bacteria, archaea, and plants can assimilate nitrate into cellular biomass. Escherichia coli and related enteric bacteria can couple the eight-electron reduction of nitrate to ammonium to growth by coupling the...
In the 纬-proteobacterium Escherichia coli , nitrate and nitrite respiration is regulated by two homologous transcription factors, NarL and NarP. Although this regulatory system was a subject of intensive research for more than 20 years, many key issues, including the structure of the NarL-binding ...
Anaerobic respiration has an important impact on the cycle of matter in nature, including processes such as denitrification (dissimilatory reduction of nitrate and nitrite to gaseous nitrogen), dissimilatory sulfate reduction with the formation of sulfide, the formation of methane and acetate from carbon...

The adaptive formation of nitrate and nitrite reductases in Micrococcus denitrificans as well as the properties and the relation between the NO 3 − and O 2 respiratory pathways have been investigated. 1. 1. Nitrate and nitrite reductases which are induced by their substrates are repressed by ...

Despite nitrite is the final product of nitrate respiration in this strain, the megaplasmid encodes two putative nitrite reductases of the cd1 and Cu-containing types, apparently inactivated by IS. No nitric oxide reductase genes have been found within this region, although the NorR sensory gene,...
These intracellular symbionts respire nitrate, i.e. they use nitrate instead of oxygen as a terminal electron acceptor in the respiratory chain. Nitrate is only reduced to nitrite and not further to nitrogen gas. Nitrate is respired by the symbionts under fully aerobic conditions at the same ...
The symbionts show constitutive anaerobic respiration, using nitrate instead of oxygen as a terminal electron acceptor. An immediate increase in heat production was observed after the addition of nitrate to the perfusion medium of the calorimeter and this was accompanied by the appearance of nitrite ...
Unlike most bacteria, the nitrogen-fixing rice-associated Pseudomonas stutzeri A15 disposes of three different nitrate reductases that enable conversion of nitrate to nitrite through three physiologically distinct processes, called nitrate assimilation, nitrate respiration and nitrate dissimilation. To study th...
