CC   -!- FUNCTION: Structural rigidity of the outer membrane of elementary
CC       bodies and porin forming, permitting diffusion of solutes through the
CC       intracellular reticulate body membrane. {ECO:0000250|UniProtKB:P80368}.
CC   -!- SUBUNIT: Disulfide bond interactions within and between MOMP molecules
CC       and other components form high molecular-weight oligomers.
CC       {ECO:0000250|UniProtKB:P80368}.
CC   -!- SUBCELLULAR LOCATION: Cell outer membrane {ECO:0000269|PubMed:8837367};
CC       Multi-pass membrane protein {ECO:0000269|PubMed:8837367}.
CC   -!- SIMILARITY: Belongs to the Gram-negative porin family. {ECO:0000305}.
