A marriage of bacteriology with cell biology results in twin arginines.
The Tat apparatus is a remarkable molecular machine required for the transmembrane translocation of folded proteins. Recent studies have identified jellyfish green fluorescent protein as an excellent reporter protein for the bacterial Tat pathway. Although the genetics of the Tat system are reasonably well-defined in Escherichia coli, the utilization of heterologous proteins as transport substrates promises to facilitate further mechanistic and structural characterization of this system.
