Development of strong promoters is of growing interest in the field of biotechnology and synthetic biology. Here we present a protocol for the construction of strong prokaryotic promoters that can be recognized by designated multiple sigma factors by interlocking their cognate binding motifs on DNA strands. Strong and stress responsive promoters for Escherichia coli and Bacillus subtilis have been created following the presented protocol. Customized promoters could be easily developed for fine-tuning gene expression or overproducing enzymes with prokaryotic cell factories.
