phiC31 attB_J23119_phiC31 attP

The constitutive promoter J23119 is between phiC31 specific sites and will be inverted by the phiC31 recombinase, thus leading to the direction of promoter and change of gene expression. This unit can be used as standard reporter of recombinase phiC31 characterization.

Usage

We constructed this part to characterize the recombination efficiency of the phiC31 integrase. It consists of a constitutive promoter (BBa_J23119) flanked by attB and attP sites of the phiC31 integrase. Upon recombination, the orientation of the constitutive promoter change. As a result, expression of downstream sequence is shut down, and upstream sequence is transcribed.

Biology

J23119 is the consensus sequence of a combinatorial constitutive promoter library family. Integrase phiC31 from phage phiC31 can recognize and bind the attP sequence on phage DNA and the attB sequence on the host chromosomal DNA, and promotes unidirectional recombination to integrate the phage DNA into the host. We obtained the promoter, attB and attP sites by oligo synthesis.

Design Notes

We construct this structure by Gibson Assembly.


Source

The Streptomyces phage

Characterization

We used this part to characterize the recombination efficiency of the integrase phiC31.
