Design Notes

This part is the LOV2 promoter driving expression of mRuby, a composite of BBa_K2805002 and BBa_K2805003. An organism expressing BBa_K2805004 will produce mRuby, a red fluorescent protein, when under a blue light (450-490 nm). This sequence is optimized for integration into S. cerevisiae


The primary concern was Dueber MoClo and GoldenGate compatibility. These sequences were designed to be robustly assembled and integrated into the S. cerevisiae genome.

Source

LOV2 was identified and engineered from E. litoralis by Laura B. Motta-Mena et al. (Nature Chemical Biology 2014, doi: 10.1038/nchembio.1430). The C120op EL222-binding sequence was first identified in E. litoralis by Giomar Rivera-Cancel, Laura B. Motta-Mena, and Kevin H. Gardner (Biochemistry 2012, doi: 10.1021/bi301306t). mRuby2 is derived from Entacmaea quadricolor, best described by Aj et al. (Nature Methods 2012, doi: 10.1038/nmeth.2171).
