Journal ArticleDOI
Cell biology and molecular basis of denitrification.
TL;DR: Denitrification is intimately related to fundamental cellular processes that include primary and secondary transport, protein translocation, cytochrome c biogenesis, anaerobic gene regulation, metalloprotein assembly, and the biosynthesis of the cofactors molybdopterin and heme D1.
Journal ArticleDOI
Phylogeny of the bacterial superfamily of Crp-Fnr transcription regulators: exploiting the metabolic spectrum by controlling alternative gene programs
TL;DR: The Crp-Fnr regulators stand out in responding to a broad spectrum of intracellular and exogenous signals such as cAMP, anoxia, the redox state, oxidative and nitrosative stress, nitric oxide, carbon monoxide, 2-oxoglutarate, or temperature.
Journal ArticleDOI
Expression of denitrification enzymes in response to the dissolved oxygen level and respiratory substrate in continuous culture of Pseudomonas stutzeri.
H Körner,Walter G. Zumft +1 more
TL;DR: The accumulation of nitrite seen during both the aerobic-anaerobic and anaerobic-aerobic transition phases was caused by the differences in onset or cessation of synthesis of nitrates and nitrite reductases and an inhibitory effect of nitrate on nitrite reduction.
Book ChapterDOI
Respiratory transformation of nitrous oxide (N2O) to dinitrogen by Bacteria and Archaea.
TL;DR: The view of evolution of N2O respiration prior to the separation of the domains Bacteria and Archaea is supported, with the paradigm of Z-type N2OR described.
Journal ArticleDOI
The biological role of nitric oxide in bacteria
TL;DR: Bacterial N oxide metabolism is related to cellular bioenergetics and processes of nitrogen assimilation, and the interest in nitric oxide (NO) centers around the dissimilatory transformation of nitrate, better known as the denitrification process.
