CC -!- FUNCTION: Part of the translocation and assembly module (TAM)
CC autotransporter assembly complex, which functions in translocation of
CC autotransporters across the outer membrane. Has anion selective
CC channel-forming ability, but the physiological relevance of this
CC activity is unclear. {ECO:0000250|UniProtKB:P0ADE4}.
CC -!- SUBUNIT: Interacts with TamB. {ECO:0000250|UniProtKB:P0ADE4}.
CC -!- SUBCELLULAR LOCATION: Cell outer membrane
CC {ECO:0000250|UniProtKB:P0ADE4}.
CC -!- DOMAIN: Contains 3 N-terminal periplasmic polypeptide transport-
CC associated (POTRA) domains and a C-terminal 16-stranded beta-barrel
CC transmembrane region. The beta-barrel is closed on the extracellular
CC face by loop 6 (residues 456-495), while the C-terminal beta-strand
CC forms an inward kink which may act as a gate for substrate access from
CC the periplasm. This kink weakens the beta-strand pair between the first
CC and last strands which may contribute to gating and substrate
CC translocation. {ECO:0000250|UniProtKB:P0ADE4}.
CC -!- DISRUPTION PHENOTYPE: Significantly reduced survival in human serum,
CC probably due to complement-mediated killing.
CC {ECO:0000269|PubMed:22466966}.
CC -!- SIMILARITY: Belongs to the TamA family. {ECO:0000305}.
