ABSTRACT
LEE-encoded effector EspF (EspF) is an effector protein part of enteropathogenic Escherichia coli's (EPEC's) arsenal for intestinal infection. This intrinsically disordered protein contains three highly conserved repeats which together compose over half of the protein's complete amino acid sequence. EPEC uses EspF to hijack host proteins in order to promote infection. In the attack EspF is translocated, together with other effector proteins, to host cell via type III secretion system. Inside host EspF stimulates actin polymerization by interacting with Neural Wiskott-Aldrich syndrome protein (N-WASP), a regulator in actin polymerization machinery. It is presumed that EspF acts by disrupting the autoinhibitory state of N-WASP GTPase binding domain. In this NMR spectroscopy study, we report the 1H, 13C, and 15N resonance assignments for the complex formed by the first 47-residue repeat of EspF and N-WASP GTPase binding domain. These near-complete resonance assignments provide the basis for further studies which aim to characterize structure, interactions, and dynamics between these two proteins in solution.
