CC -!- FUNCTION: Toxin, which has some hemolytic activity towards mammalian
CC cells. Acts by forming a pore-like structure upon contact with
CC mammalian cells (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Monomer and oligomer. In periplasm, it is present as a
CC monomer, while in outer membrane vesicles, it oligomerizes to form a
CC pore structure that is active. The pore is formed by a dodecamer (By
CC similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}. Periplasm {ECO:0000250}.
CC Host cell membrane {ECO:0000305}; Single-pass membrane protein
CC {ECO:0000305}. Note=Exported from the cell by outer membrane vesicles.
CC Also found in the periplasmic space (By similarity). {ECO:0000250}.
CC -!- PTM: In periplasm, it forms a disulfide bond, which prevents the
CC oligomerization. In outer membrane vesicles, the redox status prevents
CC formation of the disulfide bond, leading to oligomerization and pore
CC formation (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the hemolysin E family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAG56033.1; Type=Erroneous initiation; Evidence={ECO:0000305};
CC Sequence=BAB35100.1; Type=Erroneous initiation; Evidence={ECO:0000305};
CC Sequence=CAB64962.1; Type=Erroneous initiation; Evidence={ECO:0000305};
