LssmOrange is a fluorophor derived from dsRed and is a FRET partner of mKate [BBa_K1055000]
Usage and Biology
LSSmOrange is an orange fluorescent protein that we want to use for FRET, we us it as a donor. LSSmOrange has an excitation maximum by 437 nm and an emission maximum by 572 nm. The excitation maximum is at 415 nm, another at 453 nm and our measured emission maximum is at 564 nm (Fig. 2). This aberration changes nothing on the FRET system. The excitation maximum is big enough to stimulate mKate, the other fluorescent protein (Fig. 3). Of course, we also checked the emission and excitation of our E. coli BL21(DE3) cells (data not shown) and we can eliminate the theories that these cells disturb this florescence measurement.
Furthermore we did homology modeling with this part, please refer to our http://2013.igem.org/Team:TU_Darmstadt/modelling/Structure wiki page, whose best model results are illustrated below:
