Reaction of the NAD(P)H:flavin oxidoreductase from Escherichia coli with NADPH and riboflavin: identification of intermediates [PDF]

Biochemistry, American Chemical Society, 1998, 37, pp.11879-87, 2014
Flavin reductase catalyzes the reduction of free flavins by NAD(P)H. As isolated, Escherichia coli flavin reductase does not contain any flavin prosthetic group but accommodates both the reduced pyridine nucleotide and the flavin substrate in a ternary complex prior to oxidoreduction.

Development of PCR Primer Systems for Amplification of Nitrite Reductase Genes (nirK and nirS) To Detect Denitrifying Bacteria in Environmental Samples

Applied and Environmental Microbiology, 1998
A system was developed for the detection of denitrifying bacteria by the amplification of specific nitrite reductase gene fragments with PCR. Primer sequences were found for the amplification of fragments from both nitrite reductase genes (nirK andnirS ...

Human Neuroglobin Functions as a Redox-regulated Nitrite Reductase*

Journal of Biological Chemistry, 2011
Neuroglobin is a highly conserved hemoprotein of uncertain physiological function that evolved from a common ancestor to hemoglobin and myoglobin. It possesses a six-coordinate heme geometry with proximal and distal histidines directly bound to the heme ...

Redox Reactivity of Nonsymbiotic Phytoglobins towards Nitrite

Molecules
Nonsymbiotic phytoglobins (nsHbs) are a diverse superfamily of hemoproteins grouped into three different classes (1, 2, and 3) based on their sequences.

STUDIES SUGGESTING THE PRESENCE OF MORE THAN ONE NITRITE REDUCTASE IN NEUROSPORA CRASSA [PDF]

It is usually assumed that the reduction of nitrite by nitrite reductase results in the formation of ammonia. The purpose of this investigation was to enquire whether more than one nitrite reductase activity is responsible for in vivo nitrite ...

The wider perspective: Barriers and recommendations for transfusion support for patients with sickle cell disease in low‐ and middle‐income countries

British Journal of Haematology, EarlyView.
Globally, sickle cell disease (SCD) is the most common inherited haemoglobinopathy. The highest burden of SCD is encountered in low‐ and middle‐income countries (LMICs), most of which lack the resources to contend with the disease. Blood transfusion remains central to the emergent treatment and prevention of complications of SCD.

The Anti-Sigma Factor MucA of Pseudomonas aeruginosa: Dramatic Differences of a mucA22 vs. a ΔmucA Mutant in Anaerobic Acidified Nitrite Sensitivity of Planktonic and Biofilm Bacteria in vitro and During Chronic Murine Lung Infection [PDF]

, 2019
Mucoid mucA22 Pseudomonas aeruginosa (PA) is an opportunistic lung pathogen of cystic fibrosis (CF) and chronic obstructive pulmonary disease (COPD) patients that is highly sensitive to acidified nitrite (A-NO2-).

Redox cycling and kinetic analysis of single molecules of solution-phase nitrite reductase

Proceedings of the National Academy of Sciences of the United States of America, 2011
Single-molecule measurements are a valuable tool for revealing details of enzyme mechanisms by enabling observation of unsynchronized behavior. However, this approach often requires immobilizing the enzyme on a substrate, a process which may alter enzyme

Thaumarchaeal ammonium oxidation and evidence for a nitrogen cycle in a subsurface radioactive thermal spring in the Austrian Central Alps

Frontiers in Microbiology, 2014
Previous studies had suggested the presence of ammonium oxidizing Thaumarchaeota as well as nitrite oxidizing Bacteria in the subsurface spring called Franz Josef Quelle (FJQ), a slightly radioactive thermal mineral spring with a temperature of 43.6 ...

Nitrous oxide production in soil isolates of nitrate-ammonifying bacteria [PDF]

, 2012
Here we provide the first demonstration of the potential for N2O production by soil-isolated nitrate-ammonifying bacteria under different C and N availabilities, building on characterizations informed from model strains.
