outer membrane autotransporter barrel domain; A number of Gram-negative bacterial proteins, mostly found in pathogens and associated with virulence, contain a conserved C-terminal domain that integrates into the outer membrane and enables the N-terminal region to be delivered across the membrane. This C-terminal autotransporter domain is about 400 amino acids in length and includes the aromatic amino acid-rich OMP signal, typically ending with a Phe or Trp residue, at the extreme C-terminus.

Extended Signal Peptide of Type V secretion system; This conserved domain is called ESPR for Extended Signal Peptide Region. It is present at the N-terminus of the signal peptides of proteins belonging to the Type V secretion systems, including the autotransporters (T5aSS), TpsA exoproteins of the two-partner system (T5bSS) and trimeric autotransporters (TAAs). So far, the ESPR is present only in Gram-negative bacterial proteins originating from the classes Beta- and Gamma-proteobacteria. ESPR severely impairs inner membrane translocation, suggesting that it adopts a particular conformation or it interacts with a cytoplasmic or inner membrane co-factor, prior to exportation. Deletion of ESPR causes mis-folding of the TAAs passenger domain in the periplasm, substantially impairing its translocation across the outer membrane.

Autotransporter beta-domain; Secretion of protein products occurs by a number of different pathways in bacteria. One of these pathways known as the type V pathway was first described for the IgA1 protease. The protein component that mediates secretion through the outer membrane is contained within the secreted protein itself, hence the proteins secreted in this way are called autotransporters. This family corresponds to the presumed integral membrane beta-barrel domain that transports the protein. This domain is found at the C terminus of the proteins it occurs in. The N terminus contains the variable passenger domain that is translocated across the membrane. Once the passenger domain is exported it is cleaved auto-catalytically in some proteins, in others a different protease is used and in some cases no cleavage occurs.

Autotransporter beta-domain; Secretion of protein products occurs by a number of different pathways in bacteria. One of these pathways known as the type IV pathway was first described for the IgA1 protease. The protein component that mediates secretion through the outer membrane is contained within the secreted protein itself, hence the proteins secreted in this way are called autotransporters. This family corresponds to the presumed integral membrane beta-barrel domain that transports the protein. This domain is found at the C-terminus of the proteins it occurs in.

Pertactin-like passenger domains (virulence factors) of autotransporter proteins of the type V secretion system. Autotransporters are proteins used by Gram-negative bacteria to transport proteins across their outer membranes. The C-terminal (beta) domain of autotransporters forms a pore in the outer membrane through which the N-terminal passenger domain is transported. Following transport, the passenger domain is generally cleaved by an outer membrane protease with the passenger domain either remaining in contact with the surface via a noncovalent interaction with the beta domain or cleaved to release a soluble protein. These proteins are highly diverse and perform a variety of functions that promote virulence, including catalyzing proteolysis, serving as an adhesin, mediating actin-promoted motility, or serving as a cytotoxin. Proteins in this family share similarity in the C-terminal region of the passenger domain as seen in the pertactin structure P.69, a Bordetella pertussis agglutinogen responsible for human pertussis. The P.69 protein consists of a 16-stranded parallel beta-helix with a V-shaped cross-section, and is one of the largest beta-helix known to date.
