Engineering neuroglobin nitrite reductase activity based on myoglobin models
Biochemistry and Biophysics Reports, 2023 Neuroglobin is a hemoprotein expressed in several nervous system cell lineages with yet unknown physiological functions. Neuroglobin presents a very similar structure to that of the related globins hemoglobin and myoglobin, but shows an hexacoordinate ...

Crosstalk between nitrite, myoglobin and reactive oxygen species to regulate vasodilation under hypoxia. [PDF]
PLoS ONE, 2014 The systemic response to decreasing oxygen levels is hypoxic vasodilation. While this mechanism has been known for more than a century, the underlying cellular events have remained incompletely understood.

Bringing Nitric Oxide to the Molybdenum World—A Personal Perspective
Molecules, 2023 Molybdenum-containing enzymes of the xanthine oxidase (XO) family are well known to catalyse oxygen atom transfer reactions, with the great majority of the characterised enzymes catalysing the insertion of an oxygen atom into the substrate. Although some

Rhizobium etli Produces Nitrous Oxide by Coupling the Assimilatory and Denitrification Pathways
Frontiers in Microbiology, 2019 More than two-thirds of the powerful greenhouse gas nitrous oxide (N2O) emissions from soils can be attributed to microbial denitrification and nitrification processes.

Genetic and environmental controls on nitrous oxide accumulation in lakes. [PDF]
PLoS ONE, 2015 We studied potential links between environmental factors, nitrous oxide (N2O) accumulation, and genetic indicators of nitrite and N2O reducing bacteria in 12 boreal lakes.

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022 Background The enterosalivary nitrate–nitrite–nitric oxide (NO3–NO2–NO) pathway generates NO following oral microbiota‐mediated production of salivary nitrite, potentially linking the oral microbiota to reduced cardiometabolic risk.

Nature Communications, 2023 Nitrate ammonification is important for soil nitrogen retention. However, the ecology of ammonifiers and their prevalence compared with denitrifiers, being competitors for nitrate, are overlooked.

Impact of mitochondria on nitrite metabolism in HL-1 cardiomyocytes
Frontiers in Physiology, 2013 Apart from ATP synthesis mitochondria have many other functions, one being nitrite reductase activity. NO released from nitrite has been shown to protect the heart from ischemia/reperfusion injury in a cGMP-dependent manner.
