φBT1 integrase
This ORF codes for the steptomyces phage φBT1 integrase, which catalyzes a site specific recombination between φBT1 attB and attP sequences. This recombinase can be used to 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.
Biological Characterisation
φBT1 integrase is a member of the large serine recombinases(LSRs) family. LSRs are recombinases encoded by temperate phage genomes, which precisely cut and recombine DNA in a highly controllable and predictable way. The recombinases recognize and bind to attB/P sites as dimers, and cut and recombinate on the attB/P sites, with two dimers forming a Tetramer. The recombinated attB/P sites form attL and attR sites. The recombination is irreversible without the corresponding phage excisionase, making the recombination stable and reliable.
