| Glossary: |
β-seco-amyrin = 8,14-secooleana-7,13-diene-3β-ol |
| Systematic name: |
(3S)-2,3-epoxy-2,3-dihydrosqualene mutase (cyclizing, β-seco-amyrin-forming) |
| Comments: |
The enzyme from Arabidopsis thaliana is multifunctional and produces about equal amounts of α- and β-seco-amyrin. See EC 5.4.99.52, α-seco-amyrin synthase. |
