TLDR
The current understanding of the process by which N(2)O is produced and destroyed is reviewed and the potential for feeding this into new approaches for combating N( 2)O release is discussed.About:

Nitrous oxide emissions from soils: how well do we understand the processes and their controls?
Klaus Butterbach-Bahl,Elizabeth M. Baggs,Michael Dannenmann,Ralf Kiese,Sophie Zechmeister-Boltenstern +4 more
TL;DR: Improved process understanding, building on the increased use of isotope tracing techniques and metagenomics, needs to go along with improvements in measurement techniques for N2O (and N2) emission in order to obtain robust field and laboratory datasets for different ecosystem types.

Copper Active Sites in Biology

TL;DR: This review presents in depth discussions of all these classes of Cu enzymes and the correlations within and among these classes, as well as the present understanding of the enzymology, kinetics, geometric structures, electronic structures and the reaction mechanisms these have elucidated.

The unaccounted yet abundant nitrous oxide-reducing microbial community: a potential nitrous oxide sink
TL;DR: A comprehensive phylogenetic analysis of the nosZ gene coding the N2OR in genomes retrieved from public databases revealed two distinct clades of nosZ, indicating a physiological dichotomy in the diversity of N2O-reducing microorganisms.
Journal ArticleDOI
Microbial regulation of terrestrial nitrous oxide formation: understanding the biological pathways for prediction of emission rates
TL;DR: It is argued that it is urgently necessary to incorporate microbial traits into biogeochemical ecosystem modeling in order to increase the estimation reliability of N2O emissions and proposed a molecular methodology oriented framework from gene to ecosystem scales for more robust prediction and mitigation of future N1O emissions.

Ritalahti,Kirsti M. Ritalahti,Silke Nissen,Silke Nissen,Konstantinos T. Konstantinidis,Frank E. Löffler,Frank E. Löffler +16 more
TL;DR: It is demonstrated that diverse microbial taxa possess divergent nos clusters with genes that are related yet evolutionarily distinct from the typical nos genes of denitirifers, and that nondenitrifying populations with a broad range of metabolisms and habitats are potentially significant contributors to N2O consumption.

Nitrogen cycles: past, present, and future

TL;DR: In this paper, the authors compared the natural and anthropogenic controls on the conversion of unreactive N2 to more reactive forms of nitrogen (Nr) and found that human activities increasingly dominate the N budget at the global and at most regional scales, and the terrestrial and open ocean N budgets are essentially dis-connected.
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.

N 2 O release from agro-biofuel production negates global warming reduction by replacing fossil fuels
Paul J. Crutzen,Paul J. Crutzen,Paul J. Crutzen,Arvin R. Mosier,Keith Smith,Wilfried Winiwarter +5 more
TL;DR: In this paper, the relationship between the amount of N fixed by chemical, biological or atmospheric processes entering the terrestrial biosphere, and the total emission of nitrous oxide (N2O), has been re-examined, us- ing known global atmospheric removal rates and concentra- tion growth of N2O as a proxy for overall emissions.

A model of nitrous oxide evolution from soil driven by rainfall events: 1. Model structure and sensitivity
TL;DR: In this paper, a rain-event driven, process-oriented model of nitrogen and carbon cycling processes in soils was used to simulate N2O and CO2 emissions from soils.
