Part:BBa_K648017

Fast-Fusion GFP-LacZa Reporter (TEV cleavage with small 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 TEV protease 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 TEV cleavage site (BBa_K648008) followed by the smallest of the three flexible fusion protein linkers (BBa_K648005). The linker is attached to the N-terminus of the LacZa gene.
