Description
This operator/promoter sequence regulates the mer operon in Thermus thermophilus HB 27; in the absence of inorganic mercury, merR, the repressor protein (BBa_M33335) binds to this sequence, preventing transcription of the downstream operon. In the presence of inorganic mercury, merR undergoes a conformation change, unblocking this promoter and allowing the downstream operon to be transcribed.
Notes
We only knew that the promoter sequence was located 69 bp upstream of the merR operon, so we isolated the 160 bp sequence directly upstream of the operon.
