How will I recognize you? N⁸-Glycosylated nucleosides (with an 8-azaguanine or 8-aza-9-deazaguanine base moiety) are recognized by DNA polymerases for pairing with 5-methylisocytosine or 8-substituted hypoxanthine bases. The N⁹ atom of the N⁸-linked nucleosides significantly affects base-pair recognition, selective pairing (against recognition by natural bases), and the ability of the N⁸-nucleosides to form a self-complementary pair.

酶促修饰的嘌呤核苷酸在DNA中的掺入

我怎么认出你？ DNA聚合酶识别N ^8-糖基化的核苷（具有8-氮杂鸟嘌呤或8-氮杂9-脱氮鸟嘌呤碱基），以与5-甲基异胞嘧啶或8-取代的次黄嘌呤碱基配对。N ^8-连接的核苷的N ⁹原子显着影响碱基对的识别，选择性配对（反对天然碱基的识别）以及N ^8-核苷形成自互补对的能力。
