NADPH Oxidase. The enzyme is dependent on a variety of CYTOCHROMES. Cell-to-cell communication and long-distance signaling play a key role in the response of plants to pests, mechanical wounding, and extreme environmental conditions. The NADPH Oxidase Enzyme Family. 300 μM of FAD were added to WT DH and Phe693 mutants. NOX1/NADPH oxidase, a nonphagocytic isoform of reactive oxygen species–producing enzymes, is highly expressed in the colon, but the physiologic and pathophysiologic roles of this isoform are not fully understood. Activation of the NADPH oxidase complex is induced by a conformational change in the flavocytochrome, which serves as a switch. Plant NADPH oxidase has been known as a respiratory burst oxidase homolog (rboh) and is homologous to the catalytic subunit (gp91phox) of a phagocytic NADPH oxidase .
