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

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

The Mechanism of Nitrite Reductase. [PDF]
J Comput ChemABSTRACT Cytochrome 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.

Endothelial alpha globin is a nitrite reductase [PDF]
Nature 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.

Effect and potential mechanism of nitrite reductase B on nitrite degradation by Limosilactobacillus fermentum RC4 [PDF]
Current Research in Food ScienceNitrite has the potential risk of hypoxic poisoning or cancer in pickled food. In our previous study, Limosilactobacillus fermentum (L. fermentum) RC4 is effective in nitrite degradation by producing nitrite reductase B (NirB).
