The Respiratory Chain In Neisseria Species [PDF]
, 2013 This work presents the organization of respiratory chain in Neisseria species. The localization of redox proteins was determined. Lipid-modified azurin (Laz) and nitrite reductase (AniA) are mainly associated with outer membrane.

Investigating the biosynthesis of heam d1 in pseudomonas aeruginosa: a cofactor for dissimilatory nitrite reductase. [PDF]
, 2010 PhDHaem d1 is a modified tetrapyrrole unique to the periplasmic enzyme nitrite reductase where it acts in catalysing the reduction of nitrite (NO2 -) to nitric oxide (NO), as part of denitrification.

The electron transport chains of Neisseria meningitidis [PDF]
, 2007 Neisseria meningitidis contains c-type and b-type cytochromes. Oxidation of c-type and b-type cytochromes by oxygen was observed in both cells grown under aerobic and denitrifying conditions, whereas oxidation of cytochromes by nitrite was only seen in ...

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression
Hepatology, EarlyView., 2022 Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

Phylogenetics and environmental distribution of nitric oxide-forming nitrite reductases reveal their distinct functional and ecological roles. [PDF]
ISME CommunThe two evolutionarily unrelated nitric oxide-producing nitrite reductases, NirK and NirS, are best known for their redundant role in denitrification. They are also often found in organisms that do not perform denitrification.

Lowering salivary pH with sugar-containing gum augments salivary nitrite production and blood pressure reduction with dietary nitrate (beetroot juice). [PDF]
Br J Clin PharmacolAcutely lowering salivary pH (with sugar‐containing acidic gum vs. sugar‐free gum) augments salivary nitrate reduction to nitrite, plasma nitrite concentration, and blood pressure lowering with dietary nitrate. Modifying salivary pH reveals a mechanism by which the nitrate‐nitrite‐NO pathway may be upregulated/inhibited, with potential for other ...
