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.

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.
Expression of denitrification enzymes in response to the dissolved oxygen level and respiratory substrate in continuous culture of Pseudomonas stutzeri
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.

Nitric Oxide Signaling and Transcriptional Control of Denitrification Genes in Pseudomonas stutzeri
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.
The biological role of nitric oxide in bacteria

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,…
Functional Domains of NosR, a Novel Transmembrane Iron-Sulfur Flavoprotein Necessary for Nitrous Oxide Respiration
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.
