USTC/OperatorPosition

From 2007.igem.org

Different locations of an operator plays a role in determining the intensity of repression in vivo[1].Both operators with strong and weak repression are required to the gates. Therefore, we systematically tested the influence of location factor on the promoter activity.

Figure 1 Left: the influence on the promoter’s activity when a single operator is at a different position upstream of the consensus sequence. Right: the influence on the promoter’s activity when a single operator is at a different position downstream of the consensus sequence.

Figure 2 Assumed influence on solo-repression when an operator is at a different position.
