CC   -!- FUNCTION: Part of the twin-arginine translocation (Tat) system that
CC       transports large folded proteins containing a characteristic twin-
CC       arginine motif in their signal peptide across membranes. TatA could
CC       form the protein-conducting channel of the Tat system.
CC       {ECO:0000255|HAMAP-Rule:MF_00236}.
CC   -!- SUBUNIT: The Tat system comprises two distinct complexes: a TatABC
CC       complex, containing multiple copies of TatA, TatB and TatC subunits,
CC       and a separate TatA complex, containing only TatA subunits. Substrates
CC       initially bind to the TatABC complex, which probably triggers
CC       association of the separate TatA complex to form the active translocon.
CC       {ECO:0000255|HAMAP-Rule:MF_00236}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00236}; Single-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00236}.
CC   -!- SIMILARITY: Belongs to the TatA/E family. {ECO:0000255|HAMAP-
CC       Rule:MF_00236}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAN45349.1; Type=Erroneous initiation; Evidence={ECO:0000305};
CC       Sequence=AAP18849.1; Type=Erroneous initiation; Evidence={ECO:0000305};
