Mechanism-Driven Enzyme Reshaping: A Catalytic Switch Dictates Product Specificity in Sesquiterpene Synthases
Sesquiterpene synthases generate diverse terpenoid skeletons through carbocation-driven cyclization cascades. Here, we performed a comparative mechanistic study of Artemisia argyisesquiterpene synthase (AaCPS) and Zingiber zerumbet synthase 1 (ZSS1), which exhibit reversed major-product profiles. GC–MS analysis showe...
