EC 4.2.3.93 Details
show Brenda entryEC number
4.2.3.93
Accepted name
δ-guaiene synthase
Reaction
(2E,6E)-farnesyl diphosphate = δ-guaiene + diphosphate
Systematic name
(2E,6E)-farnesyl-diphosphate diphosphate-lyase (cyclizing, δ-guaiene-forming)
Comment
Requires Mg2+. In Aquilaria crassna three clones of the enzyme gave about 80% δ-guaiene and 20% α-guaiene (see also EC 4.2.3.87). A fourth clone gave 54% δ-guaiene and 45% α-guaiene [2].
The enzyme from Pogostemon cablin gives 13% δ-guaiene as well as 37% (-)-patchoulol (see EC 4.2.3.70), 13% α-guaiene (see EC 4.2.3.87), and traces of at least ten other sesquiterpenoids [1].
