pfam10671: TcpQ (This model is not part of the current CDD release)
Toxin co-regulated pilus biosynthesis protein Q
The toxin-coregulated pilus (TCP) of Vibrio cholerae and the soluble TcpF protein that is secreted via the TCP biogenesis apparatus are essential for intestinal colonisation in the disease of cholera. TcpQ is part of an outer membrane complex of the TCP biogenesis apparatus, comprised of TcpC and TcpQ, and the TcpQ is required for proper localization of TcpC to the outer membrane. The domain is found in other Proteobacterial species apart from Vibrio.
