Webb3 nov. 2010 · Twin-arginine-dependent translocation of folded proteins. Tat denotes a protein transport pathway in bacteria, archaea and plant chloroplasts, which is specific for precursor proteins harbouring a characteristic twin-arginine pair in their signal sequences, and requires the proton-motive force across the membranes. WebbIf cytosolic proteins were to bind SecB they would not enter the export pathway because they would lack a signal peptide. SecB would not become saturated with such proteins. The ligands, if unfolded, could be degraded by proteases as observed for a SecB-bound precursor that lacks a leader ( 95 ) or they might be capable of refolding on the surface …
