Figure 3From: Characterization of the iron-regulated desA promoter of Streptomyces pilosus as a system for controlled gene expression in actinomycetesPhysical map of the four vectors used to quantify iron regulation of the desA promoter. pUL99DA and pUL99ADi are multicopy vectors whereas pUL42DA and pUL42Adi are low copy number vectors; amy indicates the promoter-less amy gene; desAp corresponds to the desA promoter; xylE, catechol oxygenase gene; ter, transcriptional terminator; tsr, thiostrepton resistance gene (see Table 1).Back to article page
