Direct Electrochemistry of Redox Enzymes as a Tool for Mechanistic Studies
TL;DR: This review regards the use of dynamic electrochemistry to study the mechanism of redox enzymes, with exclusive emphasis on the configuration where the protein is adsorbed onto an electrode and electron tranfer is direct.

Metalloproteins containing cytochrome, iron-sulfur, or copper redox centers.
Jing Liu,Saumen Chakraborty,Parisa Hosseinzadeh,Yang Yu,Shiliang Tian,Igor D. Petrik,Ambika Bhagi,Yi Lu +7 more
TL;DR: Through this review, structural features responsible for their redox properties are examined, including knowledge gained from recent progress in fine-tuning the redox centers.

Microbial nitrogen cycling processes in oxygen minimum zones.
Phyllis Lam,Marcel M. M. Kuypers +1 more
TL;DR: Oxygen minimum zones (OMZs) harbor unique microbial communities that rely on alternative electron acceptors for respiration, and conditions therein enable an almost complete nitrogen (N) cycle and substantial N-loss.
Journal ArticleDOI
Pathways of nitrogen utilization by soil microorganisms - a review.
TL;DR: In this paper, the authors review the current knowledge about the regulation of the enzyme systems involved in the acquisition of N and propose a conceptual model on the factors affecting the relative importance of organic and mineral N uptake.
Journal ArticleDOI
Microbial nitrate respiration – Genes, enzymes and environmental distribution
TL;DR: It is shown that despite rapid progress in the experimental and genomic analyses of pure cultures, knowledge on the mechanism of nitrate reduction in natural ecosystems is still largely lacking.

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
The Mononuclear Molybdenum Enzymes
TL;DR: It is now well-established that all molybdenum-containing enzymes other than nitrogenase fall into three large and mutually exclusive families, as exemplified by the enzymes xanthine oxidation, sulfite oxidase, and DMSO reductase; these enzymes represent the focus of the present account.
Journal ArticleDOI
Crystal structure of the nickel–iron hydrogenase from Desulfovibrio gigas
TL;DR: The X-ray structure of the heterodimeric Ni–Fe hydrogenase from Desulfovibrio gigas, the enzyme responsible for the metabolism of molecular hydrogen, has been solved at 2.85 Å resolution and suggests plausible electron and proton transfer pathways.

TL;DR: The number of reports on unaccounted high nitrogen losses in wastewater treatment is gradually increasing, indicating that anaerobic ammonium oxidation may be more widespread than previously assumed.
Journal ArticleDOI
Anaerobic oxidation of ammonium is a biologically mediated process
TL;DR: It was concluded that anaerobic ammonium oxidation was a microbiological process as the conversion of ammonium to dinitrogen gas did not even require a trace of O2.
