ID 4.2.3.93 DE delta-guaiene synthase. CA (2E,6E)-farnesyl diphosphate = delta-guaiene + diphosphate. CC -!- In Aquilaria crassna three clones of the enzyme gave about 80% delta- CC guaiene and 20% alpha-guaiene (see also EC 4.2.3.87). CC -!- A fourth clone gave 54% delta-guaiene and 45% alpha-guaiene. CC -!- The enzyme from Pogostemon cablin gives 13% delta-guaiene as well as CC 37% (-)-patchoulol (see EC 4.2.3.70), 13% alpha-guaiene (see CC EC 4.2.3.87), and traces of at least ten other sesquiterpenoids.
