Fast-Fusion GFP-LacZa Reporter (RecA cleavage with Medium linker)

This is a fast-acting reporter using the LacZa gene (BBa_K648012) fused to GFP (BBa_K648013). In its normal un-cleaved state the polymerization ability necessary for enzymatic action is inactivated. Once the fusion protein is cleaved by the RecA protein, which is activated by the presence of damaged DNA, the B-gal enzyme encoded by the LacZa gene is able to convert X-gal to galactose and 5-bromo-4-chloro-3-hydroxyindole, the latter of which is oxidized to the dark blue product 5,5'-dibromo-4,4'-dichloro-indigo. This reporter is able to produce a visible blue color response in a matter of minutes.

This version uses the RecA cleavage site (BBa_K648009) followed by a 6 amino acid flexible fusion protein linker (BBa_K648005). The linker is attached to the N-terminus of the LacZa gene.
