CC   -!- FUNCTION: Part of the ABC transporter complex BtuCDF involved in
CC       vitamin B12 import. Involved in the translocation of the substrate
CC       across the membrane. {ECO:0000255|HAMAP-Rule:MF_01004}.
CC   -!- SUBUNIT: The complex is composed of two ATP-binding proteins (BtuD),
CC       two transmembrane proteins (BtuC) and a solute-binding protein (BtuF).
CC       {ECO:0000255|HAMAP-Rule:MF_01004}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01004}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01004}.
CC   -!- SIMILARITY: Belongs to the binding-protein-dependent transport system
CC       permease family. FecCD subfamily. {ECO:0000255|HAMAP-Rule:MF_01004}.
