Terpene cyclases (TCs) are pivotal enzymes in nature, orchestrating the intricate synthesis of terpenes, a diverse group of natural compounds with profound biological activities. This review delves into the multifaceted roles of terpene cyclases, which serve as nature’s biochemical architects, sculpting the chemical landscape of plants, fungi, and bacteria. Understanding the catalytic mechanisms of TCs unveils the astounding diversity of terpenes and their vital functions in plant defense, pollination, and growth regulation. Moreover, this review examines the classification of TCs, shedding light on their distinct classes and the array of terpenoids they produce, each with unique biological activities. Exploration of terpenes in cancer therapy uncovers their promising anti-cancer properties, targeting key hallmarks of cancer progression such as proliferation, survival, and metastasis. This review elaborates on various mechanisms through which terpenes induce apoptosis, inhibit tumor growth, modulate immune responses, and enhance chemotherapy efficacy.
