Figure 1From: Regulation of the expression level of transcription factor XylS reveals new functional insight into its induction mechanism at the PmpromoterMap of plasmid pFS7. Ps2: constitutive promoter; xylS: gene encoding Pm activator; luc: gene encoding luciferase; Pm: positively regulated promoter; bla: ampicillin resistance gene encoding β-lactamase; t 1 : rrnBT 1 T 2 bidirectional transcriptional terminator; trfA: gene encoding the replication protein; oriV: origin of vegetative replication; kan: kanamycin resistance gene; oriT: origin of conjugal transfer. The DNA sequence of the overlapping stop-start codon is depicted.Back to article page
