CC   -!- FUNCTION: Probably involved in polymerization and/or export of
CC       exopolysaccharide EPS I which functions as a virulence factor.
CC   -!- SUBCELLULAR LOCATION: Cell outer membrane {ECO:0000305}; Multi-pass
CC       membrane protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the BexD/CtrA/VexA family. {ECO:0000305}.
