Description

A mutated twi proximal element (PE) in which the core sequence of the low affinity TD5 dl binding site has been mutated to the optimal sequence to create a high affinity site (sequence of the low affinity TD4 site is unchanged), followed by twi sequence from -180 to +160bp relative to the transcription start site, are fused upstream of lacZ.
