Production, characterization and determination of the real catalytic properties of the putative "succinate dehydrogenase" from Wolinella succinogenes [PDF]
, 2009 Both the genomes of the epsilonproteobacteria Wolinella succinogenes and Campylobacter jejuni contain operons (sdhABE) that encode for so far uncharacterized enzyme complexes annotated as ‘non-classical’ succinate:quinone reductases (SQRs).

The ins and outs of metal homeostasis by the root nodule actinobacterium Frankia [PDF]
, 2014 Background: Frankia are actinobacteria that form a symbiotic nitrogen-fixing association with actinorhizal plants, and play a significant role in actinorhizal plant colonization of metal contaminated areas.

Niche differentiation in nitrogen metabolism among methanotrophs within an operational taxonomic unit [PDF]
, 2014 Background: The currently accepted thesis on nitrogenous fertilizer additions on methane oxidation activity assumes niche partitioning among methanotrophic species, with activity responses to changes in nitrogen content being dependent on the in situ ...

A functional description of CymA, an electron-transfer hub supporting anaerobic respiratory flexibility in Shewanella [PDF]
, 2012 CymA (tetrahaem cytochrome c) is a member of the NapC/NirT family of quinol dehydrogenases. Essential for the anaerobic respiratory flexibility of shewanellae, CymA transfers electrons from menaquinol to various dedicated systems for the reduction of ...

Effect of Ammonium and Nitrate on Ferric Chelate Reductase and Nitrate Reductase in Vaccinium Species [PDF]
Annals of Botany, 2004 Most Vaccinium species have strict soil requirements for optimal growth, requiring low pH, high iron availability and nitrogen primarily in the ammonium form. These soils are limited and are often located near wetlands. Vaccinium arboreum is a wild species adapted to a wide range of soils, including high pH, low iron, and nitrate-containing soils. This

The key role of nitric oxide in hypoxia: hypoxic vasodilation and energy supply-demand matching [PDF]
, 2013 Significance: a mismatch between energy supply and demand induces tissue hypoxia with the potential to cause cell death and organ failure. Whenever arterial oxygen concentration is reduced, increases in blood flow - 'hypoxic vasodilation' - occur in an ...

Nitrogen metabolism in a grapevine in vitro system
OENO One, 2002 Ammonium, nitrate, nitrite, protein and individual and total amino acid contents were determined in grapevine (cv Sauvignon) cultured in vitro. The enzyme activities of nitrate and nitrite reductases, glutamine synthetase, glutamate synthetase and ...

Cytochromes c550, c552, c1 in the electron transport network of Paracoccus denitrificans: redundant or subtly different in function? [PDF]
, 2001 Paracoccus denitrificans strains with mutations in the genes encoding the cytochrome c550, c552, or c1 and in combinations of these genes were constructed, and their growth characteristics were determined.
