CC -!- FUNCTION: Part of the ABC transporter complex HlyBD involved in
CC hemolysin export. Transmembrane domains (TMD) form a pore in the inner
CC membrane and the ATP-binding domain (NBD) is responsible for energy
CC generation (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000305}; Multi-pass
CC membrane protein {ECO:0000305}.
CC -!- DOMAIN: In HlyB the peptidase C39 domain, the ATP-binding domain (NBD)
CC and the transmembrane domain (TMD) are fused.
CC -!- MISCELLANEOUS: The complex HlyBD-TolC (OMF) forms a single transport
CC channel across the two membranes, allowing direct export of alpha-
CC hemolysin. These channel is involved in type 1 secretion system (By
CC similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the ABC transporter superfamily. Protein-1
CC exporter (TC 3.A.1.109) family. {ECO:0000305}.
CC -!- CAUTION: Tyr-9 is present instead of the conserved Cys which is
CC expected to be the active site residue of peptidase C39. Thus they are
CC presumed to be without peptidase activity. {ECO:0000305}.
