mGFPuv2

Variant of Green Fluorescent Protein (GFP) that contains the following mutations:

  • F99S/M153T/V163A: GFPuv or cycle 3 GFP was optimised for excitation by UV light (360-400nm). [1]
  • S208L: Increases the fluorescence intensity of GFPuv, resulting in GFPuv2. [2]
  • A206K: Monomerizes most GFP variants by disrupting a hydrophobic patch. [3]
MGFPuv2 can be used in difficult fusion proteins, from left to right: non-fluorescent control, INPRC-mGFPuv2 (weak promoter), mGFPuv2-streptavidin, mGFPuv2-mSA2, mGFPuv2

Usage and Biology

This combination of GFP mutations has not been reported in the literature. The UGent Belgium 2016 iGEM team used this part as a single protein and as a fusion partner with mSA2 and INPRC
