Abstract

Background: Therapeutic values of Valeriana officinalis have been associated with sesquiterpenes whose biosynthetic origins have remained enigmatic. Results: A cyclobutenyl intermediate in the catalytic cascade of valerena-1,10-diene synthase is reported. Conclusion: A new class of sesquiterpene synthases for the biosynthesis of sesquiterpenes harboring isobutenyl functional groups is proposed. Significance: Similar catalytic mechanisms from evolutionarily diverse organisms are proposed and portend sources for sesquiterpene diversity.
