CC   -!- FUNCTION: ATP-binding (A) component of a common energy-coupling factor
CC       (ECF) ABC-transporter complex. Unlike classic ABC transporters this ECF
CC       transporter provides the energy necessary to transport a number of
CC       different substrates. {ECO:0000255|HAMAP-Rule:MF_01710}.
CC   -!- SUBUNIT: Forms a stable energy-coupling factor (ECF) transporter
CC       complex composed of 2 membrane-embedded substrate-binding proteins (S
CC       component), 2 ATP-binding proteins (A component) and 2 transmembrane
CC       proteins (T component). {ECO:0000255|HAMAP-Rule:MF_01710}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_01710};
CC       Peripheral membrane protein {ECO:0000255|HAMAP-Rule:MF_01710}.
CC   -!- SIMILARITY: Belongs to the ABC transporter superfamily. Energy-coupling
CC       factor EcfA family. {ECO:0000255|HAMAP-Rule:MF_01710}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=BAA75301.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
