SOLUTION STRUCTURE OF THE PX DOMAIN FROM HUMAN P47PHOX NADPH OXIDASE
OverviewOverview
The 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.
