Identification of Amino Acid Residues within the N-Terminal Domain of EspA That Play a Role in EspA Filament Biogenesis and Function

Abstract
Enteropathogenic Escherichia coli employs a filamentous type III secretion system, made by homopolymerization of the translocator protein EspA. In this study, we have shown that the N-terminal region of EspA has a role in EspA's protein stability, interaction with the CesAB chaperone, and filament biogenesis and function.
