== Function ==
[https://www.uniprot.org/uniprot/TAMA_ECOLI TAMA_ECOLI] Part of the translocation and assembly module (TAM) autotransporter assembly complex, which functions in translocation of autotransporters across the outer membrane. Has anion selective channel-forming ability, but the physiological relevance of this activity is unclear.<ref>PMID:22466966</ref>

== Publication Abstract from PubMed ==
TamA is an Escherichia coli Omp85 protein involved in autotransporter biogenesis. It comprises a 16-stranded transmembrane beta-barrel and three POTRA domains. The 2.3-A crystal structure reveals that the TamA barrel is closed at the extracellular face by a conserved lid loop. The C-terminal beta-strand of the barrel forms an unusual inward kink, which weakens the lateral barrel wall and creates a gate for substrate access to the lipid bilayer.
