CC   -!- FUNCTION: Part of an ABC transporter complex that transports riboflavin
CC       into the cell. {ECO:0000269|PubMed:25938806}.
CC   -!- SUBUNIT: The complex is likely composed of an ATP-binding protein, a
CC       transmembrane protein (RibX) and a solute-binding protein (RibY).
CC       {ECO:0000305|PubMed:25345570}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000255}.
CC   -!- INDUCTION: Expression is probably regulated by riboflavin, via an FMN
CC       riboswitch. {ECO:0000269|PubMed:25938806}.
CC   -!- SIMILARITY: Belongs to the binding-protein-dependent transport system
CC       permease family. {ECO:0000305}.
