CC -!- FUNCTION: Required for conjugation with F-type plasmids; probably
CC serves as the mating receptor on recipient cells. {ECO:0000256|HAMAP-
CC Rule:MF_00842}.
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. {ECO:0000256|HAMAP-
CC Rule:MF_00842}.
CC -!- SUBUNIT: Monomer and homodimer. {ECO:0000256|HAMAP-Rule:MF_00842}.
CC -!- SUBCELLULAR LOCATION: Cell outer membrane
CC {ECO:0000256|ARBA:ARBA00004571, ECO:0000256|HAMAP-Rule:MF_00842};
CC Multi-pass membrane protein {ECO:0000256|ARBA:ARBA00004571,
CC ECO:0000256|HAMAP-Rule:MF_00842}. Membrane
CC {ECO:0000256|ARBA:ARBA00004141}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004141}.
CC -!- DOMAIN: The extracellular loops are most variable in sequence, and in
CC some bacteria confer sensitivity to phage and/or colicins.
CC {ECO:0000256|HAMAP-Rule:MF_00842}.
CC -!- SIMILARITY: Belongs to the outer membrane OOP (TC 1.B.6) superfamily.
CC OmpA family. {ECO:0000256|ARBA:ARBA00005710, ECO:0000256|HAMAP-
CC Rule:MF_00842}.
