Usage and Biology

We used a valencene synthase(ValS) as part of our nootkatone pathway. ValS converts FPP into Valencene. We chose the ValS from Callitropis nootkatensis, because other valencene synthases perform relatively inefficient in microorganisms[1]. For example, they show a relatively poor product specificity, are less efficient in producing sesquiterpene than other synthases and have a significant amount of side products like germacrene A. In contrast to this, ValS from C. nootkatensis has a good product specificity and is more robust in terms of pH and temperature changes. It has also a better yield than citrus valencene synthases in yeast.

This part is designed for cytosolic expression, for peroxisomal import please choose part: BBa K2271124

Characterization

We verified the expression of ValS via western blot. Therefore, we have a 3xFLAG-6xHis-Tag as a part in our plasmids, we can use for the antibodies. The estimated atomic mass of ValS is ValS is 69 kDa.

Protein abundance in WT and transformed cells from Saccharomyces cerevisiae: Protein abundance was detected using 6x His Tag Antibody. WT = wild type, ValS = Valencene Synthase, PTS1 = Peroxisom Targeting Signal 1
