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 as an ATP-driven molecular motor
CC driving the stepwise translocation of polypeptide chains across the
CC membrane. {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 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. Other proteins may also be involved.
CC {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-
CC 50. {ECO:0000255|HAMAP-Rule:MF_01382}.
CC -!- SIMILARITY: Belongs to the SecA family. {ECO:0000255|HAMAP-
CC Rule:MF_01382}.
