Title: Host cells and methods using a repressor polypeptide and an inducible promoter for gene expression

Abstract

The present invention provides for a system comprising (a) a first nucleic acid comprising a nucleotide sequence encoding a nucleotide sequence of interest operatively linked to a promoter comprising a repressor polypeptide binding site, and (b) a second nucleic acid comprising a nucleotide sequence encoding a repressor polypeptide having at least 70% amino acid identity with EilR, SmvR, KmrR, RcdA, or QacR; wherein expression of the nucleotide sequence of interest from the promoter is induced by the presence of a hydrophobic inducer, such as a hydrophobic cation inducer, such as a triarylmethane, acridine, phenazine, phenothiazine, or xanthene.
