A major wound response in grand fir (Abies grandis) sapling stems is the rapid increase in monoterpene production at the site of injury. Monoterpene cyclases (synthases) catalyze the formation of monoterpenes from geranyl pyrophosphate, and total cyclase activity increases markedly on wounding. At
The major wound-inducible monoterpene synthase (cyclase) of grand fir (Abies grandis) stems transforms geranyl pyrophosphate to both (-)-alpha-pinene (40%) and (-)-beta-pinene (60%). The enzyme was purified to apparent homogeneity by anion-exchange and hydrophobic interaction chromatography, coupled
A cell-free extract from the xylem of lodgepole pine (Pinus contorta) catalyzes the conversion of [1-3H1]geranyl pyrophosphate to a variety of monoterpene olefins found in lodgepole pine oleoresin. This monoterpene synthase activity is similar to previously described terpenoid cyclases from grand
α-Pinene is a natural and active monoterpene, which is widely used as a flavoring agent and in fragrances, pharmaceuticals, and biofuels. Although it has been successfully produced by genetically engineered microorganisms, the production level of pinene is much lower than that of hemiterpene
