Recent structural insights into the function of copper nitrite reductases. [PDF]

, 2017
Copper nitrite reductases (CuNiR) carry out the first committed step of the denitrification pathway of the global nitrogen cycle, the reduction of nitrite (NO2(-)) to nitric oxide (NO).

Ecological and genomic variation in ectomycorrhizal fungal exploration types

New Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EMF) produce mycelia with variable extension and complexity, which can be classified according to soil ‘exploration types’ (ETs). ETs have received attention as one of the few mycorrhizal trait frameworks, but without an empirical classification of ET functional diversity and environmental preferences, understanding and ...

A QM/MM Study of Nitrite Binding Modes in a Three-Domain Heme-Cu Nitrite Reductase

Molecules, 2018
Copper-containing nitrite reductases (CuNiRs) play a key role in the global nitrogen cycle by reducing nitrite (NO2−) to nitric oxide, a reaction that involves one electron and two protons.

The pleiotropic transcriptional regulator NlpR contributes to the modulation of nitrogen metabolism, lipogenesis and triacylglycerol accumulation in oleaginous rhodococci [PDF]

, 2017
The regulatory mechanisms involved in lipogenesis and triacylglycerol (TAG) accumulation are largely unknown in oleaginous rhodococci. In this study a regulatory protein (here called NlpR: Nitrogen lipid Regulator), which contributes to the modulation of

The ComEA/ComEC Operon is Critical for Nitrosative Stress Tolerance by an Oral Commensal

Molecular Oral Microbiology, EarlyView.
ABSTRACT Oral commensal streptococci play a large role in mediating microbial homeostasis. Our prior work has demonstrated that hydrogen peroxide (H2O2) produced by oral commensal streptococci can react with salivary nitrite (NO2) and generate peroxynitrite (ONOO−), a potent antimicrobial.

Convergent Valorization via Scalable C═N Bond Electrosynthesis Through Metal‐Dopant Interfacial Engineering in a Flow Electrolyzer

Angewandte Chemie, Volume 138, Issue 20, 11 May 2026.
This study establishes an innovative approach to synthesize organonitrogens featuring C═N bonds efficiently using non‐precious metal‐doped MoS2 in a flow electrolyzer. Fe dopant significantly enhances Faradaic efficiency and yield rate, achieving over 81% and 2630 mmol h−1 g−1 for formaldoxime production. This platform upcycles pollutants into valuable

Thaumarchaeal ammonium oxidation and evidence for a nitrogen cycle in a subsurface radioactive thermal spring in the Austrian Central Alps

Frontiers in Microbiology, 2014
Previous studies had suggested the presence of ammonium oxidizing Thaumarchaeota as well as nitrite oxidizing Bacteria in the subsurface spring called Franz Josef Quelle (FJQ), a slightly radioactive thermal mineral spring with a temperature of 43.6 ...

Calcium and Nitrogen Availability Controls Root Exudation in Hydroponically Cultured Barley

Plant, Cell &Environment, EarlyView.
ABSTRACT Root exudation is a key component of plant‐rhizosphere interactome. It is increasingly evident that root exudates influence rhizospheric microbial communities and in turn can benefit plants through improved resource allocation. However, how suboptimal nutrient availability relates to control of root exudation is poorly understood.
