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 ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:140785, ChEBI:CHEBI:456216;
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}.
