WebGeneral secretory ( Sec) pathway and twin-arginine translocation ( Tat) pathway assist the translocation of proteins from the cytoplasm to the membrane bound secretion systems. 4 Majority of the secreted proteins in bacteria are secreted via the Sec pathway. WebThe Tat system has a challenging task because it allows the passage of folded substrates of varying sizes while maintaining the impermeability of the membrane to ions.

DIVERSITY AND EVOLUTION OF PROTEIN TRANSLOCATION

WebAbstract. In bacteria, two major pathways exist to secrete proteins across the cytoplasmic membrane. The general Secretion route, termed Sec-pathway, catalyzes the … The twin-arginine translocation pathway (Tat pathway) is a protein export, or secretion pathway found in plants, bacteria, and archaea. In contrast to the Sec pathway which transports proteins in an unfolded manner, the Tat pathway serves to actively translocate folded proteins across a lipid membrane bilayer. In plants, the Tat translocase is located in the thylakoid membrane of the chloroplast, where it acts to export proteins into the thylakoid lumen. In bacteria, the Tat transloc…
