Because this initial discovery, there happen to be a total of 5 NOX enzymes and two dual oxidase (DUOX) enzymes found (Fig. 2A) with conserved functions. 1.2. NOX enzyme complexes create superoxide anion The NOX enzyme complexes are so named since they make use of NADPH as an electron donor to produce superoxide from molecular oxygen [12,13]. The 5 NOX enzymes (NOX1-5) and two DUOXenzymes (DUOX1-2) every have six conserved transmembrane domains and a conserved C-terminal domain with FAD and NADPH binding web pages (Fig. two). The primary catalytic units of NOX1-4 ought to type a dimer using the Superoxide-Generating NADPH Oxidase Light Chain Subunit (CYBA) for catalytic activity [20]. The activation of NOX1-3 also needs the activity of cytosolic things for activation. DUOX1 and DUOX2 have an further transmembrane domain referred to as the peroxidase-like domain (Fig. 2A). NOX5, DUOX1, and DUOX2 also have EF hand domains which are involved in calcium signaling (Fig. 2A). Following activation, the enzymeFig. 1. Reactive oxygen species generated from NADPH oxidase-derived superoxide. NADPH oxidase enzymes convert molecular oxygen into superoxide anion (O2) applying NADPH as an electron donor. Superoxide dismutase enzymes dismutate superoxide into hydrogen peroxide (H2O2), which can be converted into hydroxyl radicals (HO via the reduction of ferrous iron (Fe2+) to ferric iro.
