CC   -!- FUNCTION: Part of the twin-arginine translocation (Tat) system
CC       that transports large folded proteins containing a characteristic
CC       twin-arginine motif in their signal peptide across membranes.
CC       Together with TatC, TatB is part of a receptor directly
CC       interacting with Tat signal peptides. TatB may form an oligomeric
CC       binding site that transiently accommodates folded Tat precursor
CC       proteins before their translocation. {ECO:0000255|HAMAP-
CC       Rule:MF_00237}.
CC   -!- SUBUNIT: The Tat system comprises two distinct complexes: a TatABC
CC       complex, containing multiple copies of TatA, TatB and TatC
CC       subunits, and a separate TatA complex, containing only TatA
CC       subunits. Substrates initially bind to the TatABC complex, which
CC       probably triggers association of the separate TatA complex to form
CC       the active translocon. {ECO:0000255|HAMAP-Rule:MF_00237}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00237}; Single-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00237}.
CC   -!- SIMILARITY: Belongs to the TatB family. {ECO:0000255|HAMAP-
CC       Rule:MF_00237}.
