CC   -!- FUNCTION: Part of the ABC transporter complex BtuCDF involved in
CC       vitamin B12 import. Responsible for energy coupling to the transport
CC       system. {ECO:0000255|HAMAP-Rule:MF_01005}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=an R-cob(III)alamin(out) + ATP + H2O = ADP + an R-
CC         cob(III)alamin(in) + H(+) + phosphate; Xref=Rhea:RHEA:17873,

CC         EC=7.6.2.8; Evidence={ECO:0000255|HAMAP-Rule:MF_01005};
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_01005}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01005}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01005}.
CC   -!- SIMILARITY: Belongs to the ABC transporter superfamily. Vitamin B12
CC       importer (TC 3.A.1.13.1) family. {ECO:0000255|HAMAP-Rule:MF_01005}.
