Design Notes

During the design process we made sure to include the spacer sequences up- and downstream of the riboswitch because they influence the folding of the riboswitch. We originally did not know where the RBS was located in Spacer Region 2 so we had to verify the location by asking the authors.

Source

The T7 promoter is derived from the T7 phage. The riboswitch can be found in certain bacteria, the sequence we are using was created by White et. al. by creating a consenus sequence from different sequences of the riboswtich family¹. nanoLuc originates from the deep sea shrimp Oplophagus gracilirostris.
