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:0000256|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:0000256|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:0000256|HAMAP-Rule:MF_01382}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|HAMAP-Rule:MF_01382};
CC Peripheral membrane protein {ECO:0000256|HAMAP-Rule:MF_01382};
CC Cytoplasmic side {ECO:0000256|HAMAP-Rule:MF_01382}. Cytoplasm
CC {ECO:0000256|HAMAP-Rule:MF_01382}. Note=Distribution is 50-50.
CC {ECO:0000256|HAMAP-Rule:MF_01382}.
CC -!- SIMILARITY: Belongs to the SecA family. {ECO:0000256|ARBA:ARBA00007650,
CC ECO:0000256|HAMAP-Rule:MF_01382, ECO:0000256|RuleBase:RU003874}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
