The enzyme from Zea mays, variety Delprim, gives mainly sesquithujene with (S)-beta-bisabolene and (E)-beta-farnesene plus traces of other sesquiterpenoids, cf. EC 220.127.116.11 [(S)-beta-bisabolene synthase] and EC 18.104.22.168 (beta-farnesene synthase). It requires Mg2+ or Mn2+. The exact product ratio is dependent on which metal ion is present.
sesquithujene is the major product, the enzyme also produces (S)-beta-bisabolene, and the minor products 7-epi-sesquithujene, (Z)-alpha-bergamotene, (E)-alpha-bergamotene, sesquisabinene B, sesquisabinene A, and (E)-beta-farnesene
main product is (S)-(-)-limonene, minor products are alpha-thujene, beta-myrcene, (+)-sabinene, (-)-sabinene, alpha-terpinene, (E)-beta-ocimene, beta-phellandrene, alpha-terpinolene, gamma-terpinene, sabinene hydrate, (R)-(-)-linalool, and (S)-(1)-linalool
