In vivo dissection of the Tat translocation pathway in Escherichia coli.

Abstract excerpt

The bacterial Tat pathway is capable of exporting folded proteins carrying a special twin arginine (RR) signal peptide. By using two in vivo reporter proteins, we assessed factors that affect Tat pathway transport. We observed that, like the intact RR signal peptide, those with a KR or RK substitution were still capable of mediating the translocation of the folded green fluorescent protein (GFP). However, the...
