CC -!- FUNCTION: Part of the tripartite efflux system MacAB-TolC. MacB is a
CC non-canonical ABC transporter that contains transmembrane domains
CC (TMD), which form a pore in the inner membrane, and an ATP-binding
CC domain (NBD), which is responsible for energy generation. Confers
CC resistance against macrolides. {ECO:0000255|HAMAP-Rule:MF_01720}.
CC -!- SUBUNIT: Homodimer. Part of the tripartite efflux system MacAB-TolC,
CC which is composed of an inner membrane transporter, MacB, a periplasmic
CC membrane fusion protein, MacA, and an outer membrane component, TolC.
CC The complex forms a large protein conduit and can translocate molecules
CC across both the inner and outer membranes. Interacts with MacA.
CC {ECO:0000255|HAMAP-Rule:MF_01720}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_01720}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_01720}.
CC -!- SIMILARITY: Belongs to the ABC transporter superfamily. Macrolide
CC exporter (TC 3.A.1.122) family. {ECO:0000255|HAMAP-Rule:MF_01720}.
