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 including 5-formyltetrahydrofolate, pantothenate
CC and riboflavin. Expression of the complex plus FolT in E.coli allows 5-
CC formyltetrahydrofolate uptake; 5-formyltetrahydrofolate is not taken up
CC in the absence of FolT or the EcfA1A2T complex. {ECO:0000255|HAMAP-
CC Rule:MF_01710, ECO:0000269|PubMed:18931129,
CC ECO:0000269|PubMed:19717603}.
CC -!- SUBUNIT: Forms a stable energy-coupling factor (ECF) transporter
CC complex probably composed of 2 membrane-embedded substrate-binding
CC proteins (S component), 2 ATP-binding proteins (A component) and 2
CC transmembrane proteins (T component). This complex interacts with a
CC number of substrate-specific components, including FolT, PanT and RibU
CC for 5-formyltetrahydrofolate, pantothenate and riboflavin respectively.
CC {ECO:0000269|PubMed:18931129, ECO:0000269|PubMed:19717603}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305|PubMed:18931129,
CC ECO:0000305|PubMed:19717603}; Peripheral membrane protein
CC {ECO:0000305|PubMed:18931129, ECO:0000305|PubMed:19717603}.
CC -!- SIMILARITY: Belongs to the ABC transporter superfamily. Energy-coupling
CC factor EcfA family. {ECO:0000255|HAMAP-Rule:MF_01710}.
