STRUCTURE OF THE RAC/P67PHOX COMPLEX
OverviewOverview
p67phox is an essential part of the NADPH oxidase, a multiprotein enzyme, complex that produces superoxide ions in response to microbial infection., Binding of the small GTPase Rac to p67phox is a key step in the assembly, of the active enzyme complex. The structure of Rac.GTP bound to the, N-terminal TPR (tetratricopeptide repeat) domain of p67phox reveals a, novel mode of Rho family/effector interaction and explains the basis of, GTPase specificity. Complex formation is largely mediated by an insertion, between two TPR motifs, suggesting an unsuspected versatility of TPR, domains in target recognition and in their more general role as scaffolds, for the assembly of multiprotein complexes.
