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.

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.

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.

Autochaperone Domain Type 1; This entry represents the autochaperone domain of type 1 (AC-1) in the Type Va Secretion System (T5aSS). Autotransporters (ATs) belong to a family of modular proteins secreted by the Type V, subtype a, secretion system (T5aSS) and considered as an important source of virulence factors in lipopolysaccharidic diderm bacteria (archetypical Gram-negative bacteria). The AC of type 1 with beta-fold appears as a prevalent and conserved structural element exclusively associated to beta-helical AT passenger.

T5SS/PEP-CTERM-associated repeat; This model describes a repeat about 50 amino acids in length, appearing sometimes more than ten times in tandem in a single protein. Most proteins with this repeat have a C-terminal autotransporter domain (TIGR01414, pfam03797) and/or an N-terminal type V secretion system signal peptide (pfam13018), while others instead have a C-terminal PEP-CTERM domain (TIGR02595).
