CC   -!- FUNCTION: Toxin that seems to act by forming pores in the membrane of
CC       the cell. Has a hemolytic and a leucotoxic activity (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Toxicity requires sequential binding and synergistic
CC       association of a class S and a class F component which form
CC       heterooligomeric complexes. HlgA (class S) associates with HlgB (class
CC       F) thus forming an AB toxin in strains producing both gamma-hemolysins
CC       and leukocidins. HlgA and LukF-PV can also form a complex (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the aerolysin family. {ECO:0000305}.
