mRuby-ePTS1

Usage and Biology

This is a composite part containing the fluorescent protein mRuby targeted to the peroxisome via an enhanced PTS1 described by DeLoache et al. (2016)[1.]. PTS1 is a peroxisomal targeting signal recognized by a receptor called Pex5. Naturally, PTS1 consists of Ser-Lys-Leu (SKL) at the carboxy-terminus. Proteins harboring this C-terminal signal are imported into the peroxisome. The ePTS1 leads to an enhanced import of the taged protein. This part is designed as a peroxisomal marker for S. cerevisiea.[1.] For fluorometric and microscopic applications the optimal excitation of 559 nm and emission of 600 nm is discriped.

Experimental Design and Results

For the validation the S. cerevisiae Strain BY4742 was tranformed with this part. The cells were fixated and microscoped with an Elyra PS microscope. A typical peroxisomal localisation could be validated (Figure 1).
