CC   -!- FUNCTION: Has porin activity, forming small water-filled channels. Also
CC       has a structural role in determining cell shape and ability to grow in
CC       low-osmolarity medium.
CC   -!- SUBCELLULAR LOCATION: Cell outer membrane; Multi-pass membrane protein.
CC   -!- PTM: Contains two disulfide bonds.
CC   -!- SIMILARITY: Belongs to the outer membrane OOP (TC 1.B.6) superfamily.
CC       {ECO:0000305}.
