CC   -!- FUNCTION: Part of the ABC transporter complex BtuCDF involved in
CC       vitamin B12 import. Binds vitamin B12 and delivers it to the
CC       periplasmic surface of BtuC.
CC   -!- SUBUNIT: The complex is composed of two ATP-binding proteins (BtuD),
CC       two transmembrane proteins (BtuC) and a solute-binding protein (BtuF).
CC   -!- SUBCELLULAR LOCATION: Periplasm.
CC   -!- SIMILARITY: Belongs to the BtuF family.
