Fig. 8 in Site-directed mutagenesis of β sesquiphellandrene synthase enhances enzyme promiscuity

Fig. 8. Proposed mechanisms for the conversion of FPP into sesquiterpene products catalysed by PmSTS WT and its mutants (L454G and L454A). The scheme is derived from the proposed mechanism of monoterpenes synthases (Gatto et al., 2015; Piechulla et al., 2016). The products generated by the PmSTSΔ24WT are shown in black. New products generated by mutant L454G and L454A in this study are shown in red.
