Enzyme Information
| 4.2.3.132 |
Neoabietadiene synthase.
based on mapping to UniProt Q38710
(+)-copalyl diphosphate = neoabietadiene + diphosphate.
-!- Isolated from Abies grandis (grand fir). -!- This class I enzyme forms about equal proportions of abietadiene, levopimaradiene and neoabietadiene; see also EC 4.2.3.18 and EC 4.2.3.32. -!- An X-ray study of this multifunctional enzyme showed that the class I activity is in the alpha domain, while EC 5.5.1.12 activity (a class II activity) is in the beta and gamma domains. -!- In Pinus taeda (loblolly pine) the major product is levopimaradiene, with less abietadiene and neoabietadiene.

| 5.5.1.12 |
Copalyl diphosphate synthase.
based on mapping to UniProt Q38710
Geranylgeranyl diphosphate = (+)-copalyl diphosphate.
-!- In some plants, such as Salvia miltiorrhiza, this enzyme is monofunctional. -!- In other plants this activity is often a part of a bifunctional enzyme. -!- For example, in Selaginella moellendorffii this activity is catalyzed by a bifunctional enzyme that also catalyzes EC 4.2.3.131, while in the tree Abies grandis (grand fir) it is catalyzed by a bifunctional enzyme that also catalyzes EC 4.2.3.18.

| 4.2.3.18 |
Abieta-7,13-diene synthase.
based on mapping to UniProt Q38710
(+)-copalyl diphosphate = abieta-7,13-diene + diphosphate.
-!- Part of a bifunctional enzyme involved in the biosynthesis of abietadiene. -!- See also EC 5.5.1.12.
