Protein Classification

Sec-independent protein translocase family protein( domain architecture ID 241)

Sec-independent protein translocase family protein such as Sec-independent protein translocase proteins TatA and TatB, which are part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin-arginine motif in their signal peptide across membranes

mttA/Hcf106 family; Members of this protein family are involved in a sec independent translocation mechanism. This pathway has been called the DeltapH pathway in chloroplasts. Members of this family in E.coli are involved in export of redox proteins with a "twin arginine" leader motif.

19-78 7.33e-19

twin arginine-targeting protein translocase TatB; This model represents the TatB protein of a Sec-independent system for transporting folded proteins, often with a bound redox cofactor, across the bacterial inner membrane. TatC is the multiple membrane spanning component. TatB, like the related TatA/E proteins, appears to span the membrane one time. The tat system recognizes proteins with an elongated signal sequence containing a conserved R-R in a motif approximated by RRxFLK N-terminal to the transmembrane helix. TIGRFAMs model TIGR01409 describes this twin-Arg signal sequence. A similar system, termed Delta-pH-dependent transport, operates on chloroplast-encoded proteins.
