Characterization of the periplasmic redox network that sustains the versatile anaerobic metabolism of Shewanella oneidensis MR-1

Frontiers in Microbiology, 2015
The versatile anaerobic metabolism of the Gram-negative bacterium Shewanella oneidensis MR-1 (SOMR-1) relies on a multitude of redox proteins found in its periplasm.

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.

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 ...

Allosteric communication in Dihydrofolate Reductase: Signaling network and pathways for closed to occluded transition and back [PDF]

arXiv, 2007
E. Coli. dihydrofolate reductase (DHFR) undergoes conformational transitions between the closed (CS) and occluded (OS) states which, respectively, describe whether the active site is closed or occluded by the Met20 loop. A sequence-based approach is used to identify a network of residues that represents the allostery wiring diagram.

Sensing Nitrite through a Pseudoazurin–Nitrite Reductase Electron Transfer Relay

ChemPhysChem, 2005
AbstractNitrite is converted to nitric oxide by haem or copper‐containing enzymes in denitrifying bacteria during the process of denitrification. In designing an efficient biosensor, this enzymic turnover must be quantitatively assessed. The enzyme nitrite reductase from Alcaligenes faecalis contains a redox‐active blue copper centre and a nonblue ...

The Noncanonical Pathway for In Vivo Nitric Oxide Generation: The Nitrate-Nitrite-Nitric Oxide Pathway

Pharmacological Reviews, 2020
In contrast to nitric oxide, which has well established and important roles in the regulation of blood flow and thrombosis, neurotransmission, the normal functioning of the genitourinary system, and the inflammation response and host defense, its ...

SERR Spectroelectrochemical Study of Cytochrome cd1 Nitrite Reductase Co-Immobilized with Physiological Redox Partner Cytochrome c552 on Biocompatible Metal Electrodes.

PLoS ONE, 2015
Cytochrome cd1 nitrite reductases (cd1NiRs) catalyze the one-electron reduction of nitrite to nitric oxide. Due to their catalytic reaction, cd1NiRs are regarded as promising components for biosensing, bioremediation and biotechnological applications ...

Surface modified sulfur nanoparticles can escape the glutathione reductase mediated detoxification system in fungi [PDF]

arXiv, 2015
The antifungal effects of orthorhombic (~10 nm; spherical) and monoclinic (~50 nm; tetrapod) sulfur nanoparticles (SNPs) were studied against the NADPH-dependent glutathione reductase (GR) mediated xenobiotic detoxification system (GSH-GSSG) in filamentous fungi (Aspergillus niger as a model organism).

Nitrite Reductase 1 Is a Target of Nitric Oxide-Mediated Post-Translational Modifications and Controls Nitrogen Flux and Growth in Arabidopsis

International Journal of Molecular Sciences, 2020
Plant growth is the result of the coordinated photosynthesis-mediated assimilation of oxidized forms of C, N and S. Nitrate is the predominant N source in soils and its reductive assimilation requires the successive activities of soluble cytosolic NADH ...
