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}.
