In the last few years, researchers also investigate into integrases work with the help of their Recombination Directionality Factors (RDFs). Bxb1 gp47 is an Bxb1-encoded RDF, the product of gene 47. With gp47, Bxb1 gp35 allows the sequence to be flipped, excised, or inserted between attL and attR sites, which makes it useful for gene editing. We design a fusion protein for the integrase and its RDF. In our project, Bxb1 gp35-gp47 fusion protein can flip the sequence flanked by attL and attR site to reset the sequence flipped by Bxb1 gp35.

Usage

In the last few years, researchers also investigate into integrases work with the help of their Recombination Directionality Factors (RDFs). Bxb1 gp47 is an Bxb1-encoded RDF, the product of gene 47. With gp47, Bxb1 gp35 allows the sequence to be flipped, excised, or inserted between attL and attR sites, which makes it useful for gene editing. We design a fusion protein for the integrase and its RDF. In our project, Bxb1 gp35-gp47 fusion protein can flip the sequence flanked by attL and attR site to reset the sequence flipped by Bxb1 gp35.

Biology

Integrase Bxb1 gp35 comes from Mycobacteriophage, which allows the phage to insert its DNA into the host’s genome at host’s attP site using viral attB site. With RDF Bxb1 gp47, the recombined attL and attR can be recognized and undergo recombination, which enables the excision of phage genome. We got the sequence by de novo synthesis.


Design Notes

We assembled the Bxb1 gp35 and gp47 with a linker adapted from a recent research[1] by Gibson Assembly.
