WebbThe twin-arginine translocation (Tat) system, found in prokaryotes, chloroplasts, and some mitochondria, allows folded proteins to be moved across membranes. How this transport is achieved without significant ion leakage is an intriguing mechanistic question. WebbHere we assessed the influence of different leader peptides on the display of a premature cytoplasmic folding protein, ankyrin repeat protein (ARP), via the minor coat protein pIII. These peptides include the Sec, SRP and Tat pathways. The results demonstrated that the Sec and SRP pathways were capable of displaying the protein on the viral ...

Here we review current understanding of mechanisms … WebbA generalized overview of protein targeting that illustrates co-translational translocation to the endoplasmic reticulum and post-translational translocation to their specified locations. If no targeting sequence is present, then the synthesized protein will remain in the cytosol.
