Functional and structural characterization of the minimal Sec translocase of the hyperthermophile Thermotoga maritima.

The genome of the hyperthermophilic bacterium Thermotoga maritima contains the genes that encode core subunits of the protein translocase, a complex consisting of the molecular motor SecA and the protein conducting pore SecYE. In addition, we identified an erroneous sequence in the genome encoding for a putative secG gene. The genes of the T.
