Active-site protein dynamics and solvent accessibility in native Achromobacter cycloclastes copper nitrite reductase

IUCrJ, 2017
Microbial nitrite reductases are denitrifying enzymes that are a major component of the global nitrogen cycle. Multiple structures measured from one crystal (MSOX data) of copper nitrite reductase at 240 K, together with molecular-dynamics simulations ...

Structures of substrate- and product-bound forms of a multi-domain copper nitrite reductase shed light on the role of domain tethering in protein complexes

IUCrJ, 2020
Copper-containing nitrite reductases (CuNiRs) are found in all three kingdoms of life and play a major role in the denitrification branch of the global nitrogen cycle where nitrate is used in place of dioxygen as an electron acceptor in respiratory ...

Electrochemistry and spectroelectrochemistry of iron porphyrins in the presence of nitrite [PDF]

, 2001
The reaction of nitrite with ferric and ferrous porphyrins was examined using visible, infrared and NMR spectroscopy. Solutions of either ferric or ferrous porphyrin were stable in the presence of nitrite, with only complexation reactions being observed.

Analysis of multiple haloarchaeal genomes suggests that the quinone-dependent respiratory nitric oxide reductase is an important source of nitrous oxide in hypersaline environments [PDF]

, 2017
Microorganisms, including Bacteria and Archaea, play a key role in denitrification, which is the major mechanism by which fixed nitrogen returns to the atmosphere from soil and water.

Flavobacterium oreochromis From Farmed Tambaqui (Colossoma macropomum): Insights Into Genetic, Phenotypic and Pathogenic Diversity

Journal of Fish Diseases, EarlyView.
ABSTRACT Flavobacterium spp. are the etiological agents of columnaris disease. Although there is evidence that columnaris poses a significant threat to the farming of tambaqui (Colossoma macropomum), there remains a large gap in understanding the genetic and phenotypic diversities of columnaris‐causing bacteria (CCB).

A three-domain copper-nitrite reductase with a unique sensing loop

IUCrJ, 2019
Dissimilatory nitrite reductases are key enzymes in the denitrification pathway, reducing nitrite and leading to the production of gaseous products (NO, N2O and N2).

Enhancing tomato regeneration and genetic transformation efficiencies via exogenous chemical treatment and the GRF5 gene modulation

Journal of Integrative Plant Biology, EarlyView.
Supplementation of Driver and Kuniyuki Walnut Medium with phloroglucinol enhanced regeneration efficiency in tomato tissue culture. Heterologous expression of an Arabidopsis growth‐regulating factor gene, GROWTH‐REGULATING FACTOR5 (GRF5), in tomato improved regeneration and transformation efficiency, suggesting a synergistic effect between ...

Comparative modelling and molecular docking of nitrate reductase from Bacillus weihenstephanensis (DS45)

Journal of Taibah University for Science, 2016
Nitrate reductase catalyses the oxidation of NAD(P)H and the reduction of nitrate to nitrite. NR serves as a central point for the integration of metabolic pathways by governing the flux of reduced nitrogen through several regulatory mechanisms in plants,

Functional Traits Co-Occurring with Mobile Genetic Elements in the Microbiome of the Atacama Desert [PDF]

, 2019
Mobile genetic elements (MGEs) play an essential role in bacterial adaptation and evolution. These elements are enriched within bacterial communities from extreme environments. However, very little is known if specific genes co-occur with MGEs in extreme

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...
