Responses to toxicants of an Escherichia coli strain carrying a uspA'::lux genetic fusion and an E. coli strain carrying a grpE'::lux fusion are similar

Abstract

A transcriptional fusion of the Escherichia coli uspA promoter to luxCDABE was characterized and compared with a heat shock-responsive grpE'::lux fusion. Similarities in range and rank order of inducing conditions were observed; however, the magnitude of induction was typically greater for the grpE'::lux fusion strain.
