Comparative Characterization of σ32-Dependent Promoters for the Heat-Inducible Expression of FAST-PETase in Escherichia coli
Efficient regulation of recombinant enzyme expression is an important consideration for the development of microbial biocatalysts. Heat-inducible promoters regulated by the alternative sigma factor σ32 provide an inducer-free strategy for controlling gene expression in Escherichia coli. In this study, four σ32-dependen...
