ID 4.2.3.38 DE alpha-bisabolene synthase. CA (2E,6E)-farnesyl diphosphate = (E,R)-alpha-bisabolene + diphosphate. CC -!- While unlikely to encounter geranyl diphosphate (GDP) in vivo as it CC is localized to plastids, the enzyme can use GDP as a substrate in CC vitro to produce (+)-(4R)-limonene (cf. EC 4.2.3.20). CC -!- Induced as part of a defense mechanism in the grand fir Abies grandis CC as a response to stem wounding. CC -!- Formerly EC 4.2.3.n1.
