Reactive oxygen species (ROS) are conventionally regarded as inevitable deleterious by-products in aerobic metabolism with a few exceptions such as their significant role in host defense. The phagocyte NADPH oxidase, dormant in resting cells, becomes activated during phagocytosis to deliberately produce superoxide, a precursor of other microbicidal ROS, thereby playing a crucial role in killing pathogens. The catalytic center of this oxidase is the membrane-integrated protein gp91phox, tightly complexed with p22 phox, and its activation requires the association with p47 phox, p67phox, and the small GTPase Rac, which normally reside in the cytoplasm. Since recent discovery of non-phagocytic gp91 phox-related enzymes of the NAD(P)H oxidase (Nox) family-seven homologues identified in humans-deliberate ROS production has been increasingly recognized as important components of various cellular events. Here, we describe a current view on the molecular composition and post-translational regulation of Nox-family oxidases in animals.
