Substrate-dependent assembly of the Tat translocase as observed in live Escherichia coli cells.

PloS one - 1 Jan 2013

Rose Patrick, Fröbel Julia, Graumann Peter L, Müller Matthias

Abstract excerpt

The twin-arginine translocation (Tat) pathway guides fully folded proteins across membranes of bacteria, archaea and plant chloroplasts. In Escherichia coli, Tat-specific transport is executed in a still largely unknown manner by three functionally diverse membrane proteins, termed TatA, TatB, and TatC. In order to follow the intracellular distribution of the TatABC proteins in live E. coli cells, we have...
