Outline of Final Research Achievements |
We aimed at the development of a method to quantify geranylgeranyl-diphosphate (GGDP) and phytyl-diphosphate (PDP) in this study. First, we have tested whether geranylgeranyl transferase can conjugate GGDP and PDP to a dansylated peptide, which can be easily detected by a liquid chromatography system according to the method of Tong et al. 2013. However, this method only detect GGDP-conjugated peptide. Then, we attempted to use chlorophyll synthase activity to detect GGDP- or PDP-conjugate to chlorophyllide. However, we failed to overexpress this enzyme by an E. coli system, cultured insect cells (Sf9), and the MembraneMax cell-free expression system.
