    Discovery of promoter elements with previously unknown regulated responses is important for metabolic engineering. For example, promoters responsive to the end product can be useful to regulate expression with increasing levels of product. In addition, such promoters can be used as screens for production strain with increased titers. Use of reporter genes, such as a bioluminescent reporter
    luxCDABE
    , can facilitate promoter discovery. Here, protocols for analysis of genome-wide
    luxCDABE
    reporter gene collections in
    Escherichia coli
    are provided. Further, a protocol for using a selected
    para
    -hydroxycinnamic (pHCA)-responsive promoter as detection assay for bioproduced pHCA is provided.
