Design Notes

We engineered E. coli to produce a unique protein composed of two fluorophores - mRuby3 and cometGFP - joined by linkers each to the hinge of a glucose binding protein. This construct will undergo a conformational change upon binding to glucose such that the cometGFP portion in an excited state will transfer energy to the acceptor mRuby3 to be emitted. Quantifying this excitation/emission pair reveals the extent to which FRET and thus glucose binding that has occurred.
