Cell biology and molecular basis of denitrification.

  • Microbiology and molecular biology reviews : MMBR
  • 1 December 1997
TLDR
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. Expand
Phylogeny of the bacterial superfamily of Crp-Fnr transcription regulators: exploiting the metabolic spectrum by controlling alternative gene programs.
TLDR
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. Expand
Growth Yields in Bacterial Denitrification and Nitrate Ammonification
TLDR
Growth yield determinations with pure cultures of Paracoccus denitrificans and Pseudomonas stutzeri revealed that far less energy is converted via ATP into cell mass than expected from the free energy changes of denitrification. Expand
Expression of denitrification enzymes in response to the dissolved oxygen level and respiratory substrate in continuous culture of Pseudomonas stutzeri
TLDR
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. Expand
Nitric oxide reductases of prokaryotes with emphasis on the respiratory, heme-copper oxidase type.

TLDR
There is currently a broadening of the scope of NO functionality and an increase in awareness that other heme-based NO-metabolizing systems contribute to the overall capability of the prokaryotic cell to cope with NO both in anaerobic and aerobic environments, including the pathogen-host interface. Expand
Respiratory transformation of nitrous oxide (N2O) to dinitrogen by Bacteria and Archaea.
TLDR
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. Expand
Nitric Oxide Signaling and Transcriptional Control of Denitrification Genes in Pseudomonas stutzeri
TLDR
The data establish NO and DnrD as key elements in the regulatory network of denitrification in P. stutzeri and add to the previously identified nitrate-nitrite response mediated by the NarXL two-component system for the expression of respiratory nitrate reductase encoded by the narGHJI operon. Expand
Functional Domains of NosR, a Novel Transmembrane Iron-Sulfur Flavoprotein Necessary for Nitrous Oxide Respiration
TLDR
NosR's function was studied by its effects on N2O respiration, NosZ synthesis, and the properties of purified NosZ proteins, and its putative functions in electron donation and redox activation are discussed. Expand
The biological role of nitric oxide in bacteria
  • W. Zumft

  • Archives of Microbiology
  • 2004
Bacterial N oxide metabolism is related to cellular bioenergetics and processes of nitrogen assimilation. The interest in nitric oxide (NO) centers around the dissimilatory transformation of nitrate,Expand
