摘要
植物聚酮合酶催化起始底物(酰基辅酶A)反复地与丙二酰辅酶A进行缩合,通过C—C键的形成生成链状聚酮中间体,再经Claisen环合、Aldol环合等形式并经芳香化生成结构新颖多样的天然产物及"非天然小分子".对近年来发现的植物聚酮合酶的功能及来源、催化机制以及在合成"非天然小分子"中的应用进行综述.
Plant polyketide synthases (PKSs) catalyze iterative decarboxylative condensations of malonyl units (Claisen-type C--C bond formation) with a CoA-linked starter molecule to produce linear chain polyketide intermediates. By Claisen, aldol cyclization, or lactonization, and aromatization, the linear chain polyketide intermediates produce varied unnatural small molecules. In this review, the functions of the known plant PKSs are summarized, and the catalytic mechanisms and applica- tions of plant PKSs in the synthesis of unnatural small molecules are covered.
