CC   -!- FUNCTION: Part of the Sec protein translocase complex. Interacts with
CC       the SecYEG preprotein conducting channel. Has a central role in
CC       coupling the hydrolysis of ATP to the transfer of proteins into and
CC       across the cell membrane, serving both as a receptor for the
CC       preprotein-SecB complex and as an ATP-driven molecular motor driving
CC       the stepwise translocation of polypeptide chains across the membrane.
CC       {ECO:0000255|HAMAP-Rule:MF_01382}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H2O + cellular proteinSide 1 = ADP + phosphate +
CC         cellular proteinSide 2.; EC=7.4.2.8; Evidence={ECO:0000255|HAMAP-

CC       Note=May bind 1 zinc ion per subunit. {ECO:0000255|HAMAP-
CC       Rule:MF_01382};
CC   -!- SUBUNIT: Monomer and homodimer. 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_01382}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01382}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01382}; Cytoplasmic side {ECO:0000255|HAMAP-Rule:MF_01382}.
CC       Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01382}. Note=Distribution is 50-
