TG1 attB

This is a recombination site attB for TG1 integrase (BBa_K2460007). When used with phiBT1 attP (BBa_K2460009) and TG1 integrase, it can flip a DNA sequence flanked by attB and attP sites, as well as integrating a circular DNA with a attB/P site into a linear/circular DNA with a attP/B site. For more information about kinetic characterization and the orthogonality between the integrase and some other serine recombinase, go to TG1 integrase.

We use this part and BBa_K2460009(placed in the same deriction) as funcitional elements in BBa_K3254005, and they worked as expected, see below.

Genetic design

The composition and principle of the experimental system are indicated below. More details can be seen on the pages of BBa_K3254013 and BBa_K3254005.

Experimental Setup

The reporter plasmid contained this part and BBa_K2460009 were co-transferred into E.coli DH5α host with 6 integrase generator plasmids. Then single colonies were inoculated into M9 supplemented medium for overnight growth. Then, the cell cultures were diluted 1000-fold with M9 supplemented medium with 500 μM IPTG inducer and growth for another 20 hours. All incubations were carried out using a Digital Thermostatic Shaker maintained at 37 °C and 1000 rpm, using flat-bottom 96-well plates sealed with sealing film. Finally, The cultures were sampled for genotype PCR testing.

Results

IBR-G22 was the plasmid with TG1 attB and attP sites. The result indicates that the TG1 att sites can only be recombined by TG1 integrase. The recombined sequence is GATCAGCTCCGCGGGCAAGACCGTGCTCTTACCCAGTTGGGCGGGA.
