Other name(s): TPS5-Del1

Systematic name: (2E,6E)-farnesyl-diphosphate diphosphate-lyase (sesquithujene-forming)

Comments: The enzyme from Zea mays, variety Delprim, gives mainly sesquithujene with (S)-β-bisabolene and (E)-β-farnesene plus traces of other sesquiterpenoids, cf. EC [(S)-β-bisabolene synthase] and EC (β-farnesene synthase). It requires Mg2+ or Mn2+. The exact product ratio is dependent on which metal ion is present.
