attP site for phiC31 integrase

The attP site is the phage attachment site for the phiC31 phage. The site is recognized by phiC31 integrase. The phiC31 integrase catalyzes a unidirectional strand exchange between a 39 bp attP site and a 34 bp attB site (Groth et al., 2000). The enzyme works by making a synapse between attP and attB, making double strand breaks producing a 2 bp sticky overhang, exchanging the strands, and re-ligating them in the recombinant configuration (attL and attR).

We improved this part and characterized the kinetic characterization and the orthogonality between phiC31 and some other serine recombinase using this improved attP site (BBa_K24600011). For more information, go to Mycobacterium Phage Bxb1 gp35, DNA integrase
