Identification of a tyrosine switch in copper-haem nitrite reductases [PDF]
IUCrJ, 2018 There are few cases where tyrosine has been shown to be involved in catalysis or the control of catalysis despite its ability to carry out chemistry at much higher potentials (1 V versus NHE). Here, it is shown that a tyrosine that blocks the hydrophobic

Identification, Expression and Activity of Candidate Nitrite Reductases From Orange Beggiatoaceae, Guaymas Basin [PDF]
Frontiers in Microbiology, 2019 Orange filamentous Beggiatoaceae form massive microbial mats on hydrothermal sediments in Guaymas Basin; these bacteria are considered to oxidize sulfide with nitrate and nitrite as electron acceptors.

An investigation into the unusual linkage isomerization and nitrite reduction activity of a novel tris(2-pyridyl) copper complex [PDF]
Royal Society Open Science, 2017 The copper-containing nitrite reductases (CuNIRs) are a class of enzymes that mediate the reduction of nitrite to nitric oxide in biological systems. Metal–ligand complexes that reproduce the salient features of the active site of CuNIRs are therefore of

Nitric oxide‐forming nitrite reductases in the anaerobic ammonium oxidizer Kuenenia stuttgartiensis [PDF]
FEBS Open BioAnaerobic ammonium‐oxidizing (anammox) bacteria contribute to the global nitrogen cycle by removing fixed nitrogen from the environment. They do so via the anaerobic oxidation of ammonium to dinitrogen gas, with nitrite as terminal electron acceptor. The
