This region represents the C-terminal 120 amino acids of a family of surface-exposed bacterial proteins. YadA, an adhesin from Yersinia, was the first member of this family to be characterised. UspA2 from Moraxella was second. The Eib immunoglobulin-binding proteins from E. coli were third, followed by the DsrA proteins of Haemophilus ducreyi and others. These proteins are homologous at their C-terminal and have predicted signal sequences, but they diverge elsewhere. The C-terminal 9 amino acids, consisting of alternating hydrophobic amino acids ending in F or W, comprise a targeting motif for the outer membrane of the Gram negative cell envelope. This region is important for oligomerisation [1].

This domain is found in bacterial outer membrane lipoproteins probably involved in maintaining the structural integrity of the cell envelope [1], including Outer membrane protein assembly factor BamE from Vibrio cholerae (also known as SmpA). The lip ...
This domain is found in bacterial outer membrane lipoproteins probably involved in maintaining the structural integrity of the cell envelope [1], including Outer membrane protein assembly factor BamE from Vibrio cholerae (also known as SmpA). The lipid attachment site is a conserved N terminal cysteine residue. Sometimes found adjacent to the OmpA domain (Pfam:PF00691).
