Trace metal requirements for microbial enzymes involved in the production and consumption of methane and nitrous oxide [PDF]
, 2012 Fluxes of greenhouse gases to the atmosphere are heavily influenced by microbiological activity. Microbial enzymes involved in the production and consumption of greenhouse gases often contain metal cofactors.

Nitrate and nitrite reductase activities of Mycobacterium avium
International Journal of Mycobacteriology, 2018 Background: In spite of the fact that the standard test for nitrate reductase activity is negative for Mycobacterium avium, it can grow in a defined minimal medium with either nitrate (NO3) or nitrite (NO2) as sole nitrogen sources.

Nitrite Reductase Activity of Cytochrome c [PDF]
Journal of Biological Chemistry, 2008 Small increases in physiological nitrite concentrations have now been shown to mediate a number of biological responses, including hypoxic vasodilation, cytoprotection after ischemia/reperfusion, and regulation of gene and protein expression. Thus, while nitrite was until recently believed to be biologically inert, it is now recognized as a potentially

Influence of lead on N03 uptake and reduction in cucumber seedlings
Acta Societatis Botanicorum Poloniae, 2014 The influence of PbCl2 on NO3- uptake and activity level of nitrate (NR) and nitrite MR) reductases in cotyledons and roots of cucumber seedlings was studied.

Intramolecular Electron Transfer in Nitrite Reductases [PDF]
ChemPhysChem, 2005 AbstractThe copper‐ and heme‐containing nitrite reductases (NiRs) are key enzymes in denitrification. Their subunits contain two distinct redox‐active metal centers, an electron‐accepting site and a nitrite‐reducing site, to carry out the single‐electron reduction of nitrite to nitic oxide. Catalytic cycles of both enzyme families employ intramolecular

Isoform-Specific NO Synthesis by Arabidopsis thaliana Nitrate Reductase
Plants, 2019 Nitrate reductase (NR) is important for higher land plants, as it catalyzes the rate-limiting step in the nitrate assimilation pathway, the two-electron reduction of nitrate to nitrite.
