TvSDR1 for the cytosolic expression

In Thymus vulgaris, GPP is converted to γ-terpinene by the γ-terpinene synthase 1 (TvGTPS1: BBa_K4188028 + PTS1, BBa_K4188019), it is oxidized by a cytochrom P450 monooxygenase (CYP) of the 71D family (TvCYP71D179: BBa_K4188018) to a dienol intermediate. This intermediate is reduced by the short chain dehydrogenase 1 (TvSDR1: BBa_K4188017) to an instable allylic ketone intermediate which rearranges to thymol (Krause et al. 2021). The gene is MoClo (RFC1000) compatible.

Figure 1: Biosynthesis of thymol. Geranyl pyrophosphate (GPP) is converted to γ-terpinen by the Thymus vulgaris γ-terpinen-synthase 1 (TvGTPS1). Further conversion to a dienol intermediate is mediated by thymes CYP71D179. The T. vulgaris short chain dehydrogenase (TvSDR1) converts the dienol intermediate to an instable allylic ketone which rearranges to thymol.
