Design Notes

As for the different sequences used in our construction, here it is a brief description of each one:

- cI promoter (Part: BBa_R0051): The cI regulated promoter is based on the pR promoter from bacteriophage lambda. The promoter has two DNA binding sites for lambda cI repressor BBa_C0051. cI binding results in repression of transcription. The specific sequence used here is based on the cI repressible promoter used in the Elowitz repressilator.

- RybB asRNA: Taken from Bouvier et al. (2008). The device includes a RBS followed by the RybB asRNA and a terminator.


Source

It's a composite part which comes from different genes forming the bassic flip-flop with anothers improvements. According to Design Notes, the main source was the Registry of Standard Biological Parts although also nbci database was used to the following parts: LacI and SspB. Besides Tag sequences (DAS4, asRNA and OmpN fusion) were obtained from each articles (see references).
