CC   -!- FUNCTION: With TolR probably plays a role in maintaining the position
CC       of the peptidoglycan cell wall in the periplasm. Acts as a porin with
CC       low permeability that allows slow penetration of small solutes; an
CC       internal gate slows down solute passage.
CC       {ECO:0000250|UniProtKB:P0A910}.
CC   -!- SUBUNIT: Monomer and homodimer. {ECO:0000250|UniProtKB:P0A910}.
CC   -!- SUBCELLULAR LOCATION: Cell outer membrane
CC       {ECO:0000250|UniProtKB:P0A910}; Multi-pass membrane protein
CC       {ECO:0000250|UniProtKB:P0A910}.
CC   -!- DOMAIN: The extracellular loops are most variable in sequence, and in
CC       some bacteria confer sensitivity to phage and/or colicins.
CC       {ECO:0000250|UniProtKB:P0A910}.
CC   -!- SIMILARITY: Belongs to the outer membrane OOP (TC 1.B.6) superfamily.
CC       OmpA family. {ECO:0000305}.
