X-RAY STRUCTURE OF THE GENERAL SECRETION PATHWAY COMPLEX OF THE N-TERMINAL DOMAIN OF EPSE AND THE CYTOSOLIC DOMAIN OF EPSL OF VIBRIO CHOLERAE

Overview

Gram-negative bacteria use type II secretion systems for the transport of, virulence factors and hydrolytic enzymes through the outer membrane. These, sophisticated multi-protein complexes reach from the pore in the outer, membrane via the pseudopilins in the periplasm and a multi-protein, inner-membrane sub-complex, to an ATPase in the cytoplasm. The human, pathogen Vibrio cholerae uses such a secretion machinery, called the, Eps-system, for the export of its major virulence factor cholera toxin, into the intestinal tract of the human host. Here, we describe the 2.4 A, structure of the hetero-tetrameric complex of the N-terminal domain of the, ATPase EpsE and the cytoplasmic domain of the inner membrane protein EpsL, which constitute the major cytoplasmic components of the Eps-system. A, ... [(full description)]
