NADPH oxidase
ENZYME COMPLEX OF WHICH THE CORE IS A HETERODIMER COMPOSED OF A LIGHT (ALPHA) AND HEAVY (BETA) CHAIN, AND REQUIRES SEVERAL OTHER WATER-SOLUBLE PROTEINS OF CYTOSOLIC ORIGIN FOR ACTIVITY
Nadph oxidase; NAD(P)H oxidase; EC 1.6.3.1; NAD(P)H:oxygen oxidoreductase
NADPH oxidase (nicotinamide adenine dinucleotide phosphate oxidase) is a membrane-bound enzyme complex that faces the extracellular space. It can be found in the plasma membrane as well as in the membranes of phagosomes used by neutrophil white blood cells to engulf microorganisms.
