B0031-gp35-Terminator

Bxb1 gp35 is a serine integrase in Mycobacterium phage Bxb1. This intergrase can exclusively catalyze site-specific recombination between attB and attP, the attachment sites on phage chromosome and host chromosome. This recombination results in the reverse of the sequence between attB and attP, changing the two sites to attL and attR at the meantime. This inversion can be reversible by appropriately controlling the conditional expression of integrase and an excisionase in Bxb1 named gp47 at certain ratio. We change start codon ATG to GTG for a appropriate expression quantity.
