• 180,000 terpenoid compounds have been reported to date [1][2][3][4]. One of the most intriguing point is that all diversified structures are synthesized from common starting materials, isoprenoids. Reactions that generate complex cyclic structures and multiple stereocenters from linear achiral precursors

• /surrogate redox partners or fusing CYPs with redox partners [80][136][141][150][151]. One common observation is that CYP activity is not able to match the high flux of isoprenoids, leaving a significant portion of terpenes unmodified. Solutions to this problem, such as in silico redox partner prediction

• , fragrances, fuels and fuel additives. Central building blocks of all terpenes are the isoprenoid compounds isopentenyl diphosphate and dimethylallyl diphosphate. Bacteria like Escherichia coli harbor a native metabolic pathway for these isoprenoids that is quite amenable for genetic engineering. Together

Apart from bioactive compounds with applications as drugs/pharmaceuticals [4] or in the nutrition or agricultural sector, isoprenoids of minor structural complexity are used as bulk chemicals or fuel additives [5][6]. To

• identify new isoprenoids of industrial relevance essential oil extracts are screened for bioactive properties that may furnish future drugs [7][8]. Harnessing isoprenoid compounds for large-scale industrial purposes can be hampered due to low natural occurrence. Being mostly secondary metabolites

• of the nitrogenous bisphosphonates including risedronate (3) and zoledronate (4), which are widely used for treatment of osteoporosis [2]. It can be argued that the success of these drugs is due at least in part to the central roles that isoprenoids play in mammalian metabolism, which suggests that
