evolution
the phenylpropene-forming isoeugenol, IGS, synthase belongs to a structural family of NADPH-dependent reductases that also includes eugenol synthase, EGS, pinoresinollariciresinol reductase, isoflavone reductase, and phenylcoumaran benzylic ether reductase, evolution and function of EGS1 and IGS1, overview
malfunction
-
the IGS gene of Petunia axillaris subsp. parodii contains a frame-shift mutation that renders it inactive. In the absence of IGS activity the coniferyl acetate substrate is converted to dihydroconiferyl acetate, instead that eugenol synthesis is increased, overview
physiological function
additional information
distribution of aromatic volatiles in different parts of the carrot plants, overview
-
plants synthesize the volatile phenylpropene compounds eugenol and isoeugenol to serve in defense against herbivores and pathogens and to attract pollinators. Clarkia breweri flowers emit a mixture of eugenol and isoeugenol. Eugenol and isoeugenol differ in the position of the double bond in the propene side chain
physiological function
-
plants synthesize the volatile phenylpropene compounds eugenol and isoeugenol to serve in defense against herbivores and pathogens and to attract pollinators. Petunia hybrida flowers emit mostly isoeugenol with small amounts of eugenol. Eugenol and isoeugenol differ in the position of the double bond in the propene side chain
physiological function
t-anol/isoeugenol synthase is an NADPH-dependent enzyme that can biosynthesize t-anol and isoeugenol from coumaryl acetate and coniferyl acetate, respectively
physiological function
eugenol/isoeugenol synthase (DcE(I)GS1) is an NADPH-dependent enzyme that converts coniferyl acetate to eugenol. This enzyme exhibits dual product specificity and yields propenylphenol isoeugenol alongside allylphenol eugenol
