Rci recombinase system

This is the protein genertor of Rci site-specific recombinase BBa_K361000, for which a promotor and a ribosome binding site are linked on the left flank and a double bidirectional terminator on the right flank of the rci gene.

Performance

Here is our system leading to the generation of Rci site-specific recombinase (yellow in colour)

Validation
In theory, with the use of repeat A at both ends of the message as shown in Fig. 2, there exists only two possible outcomes - a single inversion or double inversion.

With two sets of primers specifically designed for the amplification of both the single inversion product and double inversion product, the amplified DNA were then subjected to DNA sequencing. Both expected results are identified, however a few ambiguous bases were identified in the DNA sequencing process as shown in Fig. 3, this may due to the limitation of the sanger sequencing method or mutations along the growth of bacteria.

To conclude, since the majority of the sequence could be recovered, the Rci system was functioning correctly in our experiment.
