Summary NADPH oxidase cytochrome b558 consists of two subunits, gp91-phox and p22-phox, defects of which result in chronic granulomatous disease (CGD). The nature of the interaction between these subunits has yet to be determined. Absence of p22-phox in autosomal CGD patient-derived B-cell lines results in detectable levels of an incompletely glycosylated gp91-phox precursor. We have detected this same precursor species in four cell lines from patients with the X-linked form of the disease due to mutations in gp91-phox. Such mutations should delineate regions of gp91-phox important for its biosynthesis, including stable association with p22-phox. One mutation mapped to the putative FAD-binding domain, one mapped to a potential haem-binding domain, and two involved the region encoded by exon 3.
