SOLUTION STRUCTURE OF THE PX DOMAIN FROM HUMAN P47PHOX NADPH OXIDASE
Structural highlights
DiseaseNCF1_HUMAN Defects in NCF1 are the cause of chronic granulomatous disease autosomal recessive cytochrome-b-positive type 1 (CGD1) [MIM:233700. Chronic granulomatous disease is a genetically heterogeneous disorder characterized by the inability of neutrophils and phagocytes to kill microbes that they have ingested. Patients suffer from life-threatening bacterial/fungal infections.[1] [2] FunctionNCF1_HUMAN NCF2, NCF1, and a membrane bound cytochrome b558 are required for activation of the latent NADPH oxidase (necessary for superoxide production).[3] Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedThe phox homology (PX) domain is a novel protein module containing a conserved proline-rich motif. We have shown that the PX domain isolated from the human p47phox protein, a soluble subunit of phagocyte NADPH oxidase, binds specifically to the C-terminal SH3 domain derived from the same protein. The solution structure of p47 PX has an alpha + beta structure with a novel folding motif topology and reveals that the proline-rich motif is presented on the molecular surface for easy recognition by the SH3 domain. The proline-rich motif of p47 PX in the free state adopts a distorted left-handed polyproline type II helix conformation.
