Superoxide is instrumental in the killing of microorganisms by phagocytic cells. It is generated by the NADPH oxidase system, a membrane-bound electron transport complex which pumps electrons from NADPH in the cytoplasm across the wall of the phagocytic vacuole to molecular oxygen.

The NADPH Oxidase and the Phagosome
2020The key purpose of phagocytosis is the destruction of pathogenic microorganisms. The phagocytes exert a wide array of killing mechanisms that allow mastering the vast majority of pathogens. One of these mechanisms consists in the production of reactive oxygen species inside the phagosome by a specific enzyme, the phagocyte NADPH oxidase. This enzyme is

The NADPH oxidase of phagocytes catalyzes the conversion of oxygen to O2(-). This multicomponent enzyme complex contains five essential protein components, two in the membrane and three in the cytosol. Unassembled and inactive in resting phagocytes, the oxidase becomes active after translocation of cytosolic components to the membrane to assemble a ...

The mechanism by which reactive oxygen species (ROS) are produced by tumour cells remained incompletely understood until the discovery over the last 15 years of the family of NADPH oxidases (NOXs 1–5 and dual oxidases DUOX1/2) which are structural homologues of gp91phox, the major membrane-bound component of the respiratory burst oxidase of leucocytes.

NADPH oxidases have a distinct cellular localization in the kidney. Reactive oxygen species (ROS) are produced in the kidney by fibroblasts, endothelial cells (EC), vascular smooth muscle cells (VSMC), mesangial cells (MCs), tubular cells, and podocyte cells.

A burst of plant NADPH oxidases
Trends in Plant Science, 2012Reactive oxygen species (ROS) are highly reactive molecules able to damage cellular components but they also act as cell signalling elements. ROS are produced by many different enzymatic systems. Plant NADPH oxidases, also known as respiratory burst oxidase homologues (RBOHs), are the most thoroughly studied enzymatic ROS-generating systems and our ...

NADPH oxidase is an enzyme that catalyzes the production of superoxide from oxygen and NADPH. It is a complex enzyme consisting of two membrane-bound components and three components in the cytosol, plus rac 1 or rac 2. Activation of the oxidase involves the phosphorylation of one of the cytosolic components.

Role of Nadph Oxidase in Atherosclerosis
Future Cardiology, 2008Reactive oxidant species (ROS) seem to play a key role in the atherosclerotic process via a series of molecular changes that lead to macrophage infiltration in the endothelium and eventually to plaque formation. ROS are also implicated in arterial dysfunction via inactivation of nitric oxide, a potent vasodilator and antiaggregating molecule produced ...

Reactive oxygen species (ROS) are highly reactive oxygen derivatives. Initially, they were considered as metabolic by-products (of mitochondria in particular), which consistently lead to aging and disease. Over the last decades, however, it became increasingly apparent that virtually all eukaryotic cells possess specifically ROS-producing enzymes ...
