pdDronpa mutant

Dronpa is a reversible photoswitchable fluorescent protein that is switched on by default “fluorescent” and is switched off when illuminated by cyan light (~500nm). Dronpa Fluorescence is recovered by shining violet light (~400nm). And has been used in a design that facilitates the optical control of protein activities

This part contains a device of two copies of Dronpa Fluorescent Protein that are codon optimized for E Coli with two BsaI cutting site in between to allow the insertion of various proteins to be tested . This coding sequence of the 2 dronpa domains has 2 mutations I4V and R149H in the first dronpa domain and an F78S mutation in the second domain that were obtained by error prone PCR. which makes it a better version of the part that already exists in the registry. here

This mutant version of Dronpa has showed a better performance than the wild type in controling the activity of both TetR [fig1] and β-galactosidase[fig 3], the work flow of the β-galactosidase activity experiment is indicated in figure 2

Figure 1:Results of the cell-free experiment. Each promoter was tested with its cognate repressors. Top: Testing with TetR caged with either wt-Dronpa (BBa_K2510108) or a mutated version(BBa_K2510109)Middle: Testing with P22c2 caged with either wt-Dronpa (BBa_K2510112) or a mutated version(BBa_K2510113).Bottom: Testing with HKcI caged with either wt-Dronpa (BBa_K2510110) or a mutated version(BBa_K2510111) Figure 2: An overview of the experiment done to evaluate the activity of β-galactosidase-Dronpa fusion. Figure 3: X-Gal grayscale picture, testing the activity of β-galactosidase fusion with both wtDronpa and mutDronpa, indicating that β-galactosidase-mutDronpa fusion is more responsive to cyan light than the β-galactosidase-wtDronp.
