Figure 5From: Development of a Fur-dependent and tightly regulated expression system in Escherichia colifor toxic protein synthesisA. A schematic diagram of the mechanism of tight Fur-dependent iron-limitation regulation switch developed for E. coli stains. The mechanism is described in Results and Discussion. B. Physical map of the pYPfhuA1 expression vector. Y, different replicate origins; MCS, multi-cloning sites; rrnBT1T2, ribosomal terminators T1 and T2.Back to article page
