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. Together with
CC TatC, TatB is part of a receptor directly interacting with Tat signal
CC peptides. TatB may form an oligomeric binding site that transiently
CC accommodates folded Tat precursor proteins before their translocation.
CC {ECO:0000256|HAMAP-Rule:MF_00237}.
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:0000256|HAMAP-Rule:MF_00237}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|HAMAP-Rule:MF_00237};
CC Single-pass membrane protein {ECO:0000256|HAMAP-Rule:MF_00237}.
CC Membrane {ECO:0000256|ARBA:ARBA00004167}; Single-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004167}.
CC -!- SIMILARITY: Belongs to the TatB family. {ECO:0000256|HAMAP-
CC Rule:MF_00237}.
