Overproduction and dissection of proteins by the expression-cassette polymerase chain reaction.

We report an efficient, general approach for the construction of protein-overproducing strains of Escherichia coli. The method, expression-cassette polymerase chain reaction (ECPCR), allows the insertion of virtually any contiguous coding sequence between sequences that direct high-level protein biosynthesis in E. coli. The gene expression cassettes… CONTINUE READING
