Endothelial alpha globin is a nitrite reductase [PDF]

open access: yesNature Communications, 2022
In mammals, hypoxia causes dilation of small arteries for increased metabolic demand. Keller et al used novel transgenic mice to show alpha hemoglobin in endothelium, once thought only in red blood cells, can regulate hypoxic-mediated dilation.

Protein NirP1 regulates nitrite reductase and nitrite excretion in cyanobacteria [PDF]

open access: yesNature Communications
When the supply of inorganic carbon is limiting, photosynthetic cyanobacteria excrete nitrite, a toxic intermediate in the ammonia assimilation pathway from nitrate.

Engineering neuroglobin nitrite reductase activity based on myoglobin models [PDF]

open access: yesBiochemistry 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 ...

An In Silico Analysis of Synthetic and Natural Compounds as Inhibitors of Nitrous Oxide Reductase (N2OR) and Nitrite Reductase (NIR) [PDF]

open access: yesToxics, 2023
Nitrification inhibitors are recognized as a key approach that decreases the denitrification process to inhibit the loss of nitrogen to the atmosphere in the form of N2O.

The Mechanism of Nitrite Reductase. [PDF]

open access: yesJ Comput Chem
ABSTRACTCytochrome c nitrite reductase (CcNiR) activates nitrite and produces ammonia. It is one of several enzymes that use a redox‐active cofactor to perform its reaction. In this case, the cofactor has a heme with a lysine as the proximal ligand and a charged nearby arginine. The role of a tyrosine, which is also close, has been less clear.

Resequencing and transcriptomic analysis reveal differences in nitrite reductase in jujube fruit (Ziziphus jujuba Mill.) [PDF]

open access: yesPlant Methods, 2021
Background Jujube is a typical fruit tree species from China. ‘Muzao’, a cracking-susceptible cultivar, and ‘Linhuang No. 1’, a cracking-resistant cultivar, were selected in a previous study as contrasting research materials.

Immunocytochemical Localization of Nitrite Reductase in Green Algae [PDF]

open access: bronzePlant Physiology, 1991
The distribution of nitrite reductase (EC 1.7.7.1) in the green algae Chlamydomonas reinhardtii, Monoraphidium braunii, Chlorella fusca, and Scenedesmus obliquus was studied by immunoelectron microscopy. The labeling of ultrathin cryosections was performed with anti-nitrite reductase antibodies followed by gold-labeled goat anti-rabbit antibodies. In C.

Structure and mechanism of copper–carbonic anhydrase II: a nitrite reductase [PDF]

open access: yesIUCrJ, 2020
Nitric oxide (NO) promotes vasodilation through the activation of guanylate cyclase, resulting in the relaxation of the smooth muscle vasculature and a subsequent decrease in blood pressure.
