The conifer Picea abies (Norway spruce) defends itself against herbivores and pathogens with a terpenoid-based oleoresin composed chiefly of monoterpenes (C(10)) and diterpenes (C(20)). An important group of enzymes in oleoresin biosynthesis are the short-chain isoprenyl diphosphate synthases that produce

A mix-and-read FlashPlate (PerkinElmer, Waltham, MA) assay for the enzyme farnesyl pyrophosphate (FPP) synthase (FPPS) was developed to rapidly measure both steps in the synthesis of FPP from dimethylallyl pyrophosphate (DMAPP). The assay used either DMAPP or geranyl pyrophosphate (GPP)
The biosynthetic pathway of the off-flavour terpenoid alcohol 2-methylisoborneol (2-MIB) requires geranyl pyrophosphate methyltransferase (GPPMT) to methylate GPP before the cyclization reaction. GPPMT is the first example of an S-adenosyl-L-methionine-dependent methyltransferase that acts on general intermediates such as geranyl pyrophosphate
Terpenes (isoprenoids), derived from isoprenyl pyrophosphates, are versatile natural compounds that act as metabolism mediators, plant volatiles, and ecological communicators. Divergent evolution of homomeric prenyltransferases (PTSs) has allowed PTSs to optimize their active-site pockets to achieve catalytic fidelity and diversity.

Hexaamide receptor 4 and coumarin phosphate 5 form an ensemble for effective sensing of geranyl pyrophosphate (GPP). Fluorescence resonance energy transfer in the 4 + 5 ensemble diminishes when 5 is replaced by GPP. Receptor 4 binds selectively with GPP
