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. Required for
CC PhoD secretion. The cytosolic fraction of TatAd binds the precursor of
CC PhoD. {ECO:0000255|HAMAP-Rule:MF_00236, ECO:0000269|PubMed:18029357}.
CC -!- SUBUNIT: Forms a complex with TatCd. Two types of complexes exist: one
CC composed of TatAd and TatCd, and another composed only of TatAd.
CC Soluble TatAd forms homomultimers bigger than 100 kDa. Soluble TatAd
CC associates in homomultimeric micelle-like particles with a size of
CC about 12 or 25 nm in diameter as well as in elongated particles of 12
CC nm in diameter. {ECO:0000255|HAMAP-Rule:MF_00236,
CC ECO:0000269|PubMed:16678787, ECO:0000269|PubMed:18029357}.
CC -!- SUBCELLULAR LOCATION: Cell membrane; Single-pass membrane protein.
CC Cytoplasm, cytosol. Note=At the onset of phosphate starvation,
CC substantial amounts of TatAd are present in the cytosol. Upon ongoing
CC starvation, the amount of TatAd in the cytosol decreases.
CC -!- INDUCTION: Expressed under conditions of phosphate starvation.
CC -!- MISCELLANEOUS: B.subtilis possesses two minimal, substrate-specific,
CC Tat translocases: TatAd-TatCd and TatAy-TatCy, each one composed of a
CC TatA and a TatC protein. TatA is bifunctional and performs the function
CC of both the TatA and TatB proteins of Gram-negative organisms.
CC -!- MISCELLANEOUS: Membrane-localization and maintenance of TatAd is
CC assisted by TatCd.
CC -!- SIMILARITY: Belongs to the TatA/E family. {ECO:0000255|HAMAP-
CC Rule:MF_00236}.
