- *Abstract
-
The invention describes a genetic method for monitoring protein folding directly in bacterial cells. Using recombinant DNA technology, a "target" protein of interest can be cloned into a reporter plasmid and introduced into bacteria. The novelty of the invention is that the "target" protein is specifically targeted to the twin-arginine translocation (tat) pathway of Escherichi coli using a highly specific signal sequence. Since the tat pathway has the inherent ability to selectively transport only those proteins which have folded properly (e.g., have a high degree of stable secondary structure), the act of transport can be used as a readout for the folding status of the "target" protein. Whereas all existing cellular screens for protein folding reply on indirect measure of protein folding, this is the first genetic screen of its type which assays protein folding directly.
