Abstract:Phagocyte oxidase plays an essential role in the first line of host defense against pathogens. It oxidizes intracellular NADPH to reduce extracellular oxygen to produce superoxide anions for pathogen killing. The resting phagocyte oxidase is a heterodimeric complex formed by two transmembrane proteins NOX2 and p22. Despite the functional importance of this complex, its structure remains elusive. Here we reported the cryo-EM structure of the human NOX2-p22 complex in nanodisc in the resting state. The structure… Show more
