CC   -!- FUNCTION: Part of the Sec protein translocase complex. Interacts with
CC       the SecYEG preprotein conducting channel. SecDF uses the proton motive
CC       force (PMF) to complete protein translocation after the ATP-dependent
CC       function of SecA. {ECO:0000255|HAMAP-Rule:MF_01463}.
CC   -!- SUBUNIT: Forms a complex with SecF. Part of the essential Sec protein
CC       translocation apparatus which comprises SecA, SecYEG and auxiliary
CC       proteins SecDF-YajC and YidC. {ECO:0000255|HAMAP-Rule:MF_01463}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01463}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01463}.
CC   -!- SIMILARITY: Belongs to the SecD/SecF family. SecD subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01463}.
