Pb2+ 和 Zn2+ 离子是活化鸟苷酸衍生物鸟苷 5'-磷咪唑的多胞苷酸定向聚合的有效催化剂。产品包括长度为 30 至 40 个单位的低聚物。当 Pb2+ 为催化剂时,核苷酸残基主要以 2'-5' 连接,而在 Zn2+ 存在时,主要以 3'-5' 连接。讨论了这些结果在 RNA 聚合酶的生命起源进化背景下的重要性。
The Pb2+and Zn2+ions are efficient catalysts for the polycytidylic acid-directed polymerization of an activated guanylic acid derivative, guanosine 5′-phosphorimidazolide. The products include oligomers of 30 to 40 units in length. The nucleotide residues are predominantly 2′-5′ linked when Pb2+is the catalyst, and predominantly 3′-5′ linked in the presence of Zn2+. The significance of these results in the context of the prebiotic evolution of RNA polymerase is discussed.
