DNA聚合酶-引物酶一直被认为是真核细胞中主要的(如果不是唯一的)复制性DNA聚合酶。然而,最近的实验提供了间接证据,证明第二种DNA聚合酶可能在DNA复制中起作用。为了鉴定哺乳动物细胞中DNA合成所必需的细胞蛋白,我们一直在研究为复制猴病毒40 DNA而开发的无细胞系统。在本报告中,我们提供了直接证据,证明除了DNA聚合酶-引物酶复合体外,还需要第二种DNA聚合酶才能有效地复制含有猴病毒40起源的DNA。该DNA聚合酶活性不受抑制DNA聚合酶α活性的单克隆抗体的影响,并且对抑制剂[N2-(p-n-丁基苯基)-9-(2-脱氧- β -d -核糖呋喃基)鸟嘌呤5'-三磷酸]具有相对抗性。此外,聚合酶的活性高度依赖于辅助蛋白,即增殖细胞核抗原。这些特征与第二个DNA聚合酶是DNA聚合酶delta的假设是一致的。
DNA polymerase alpha-primase has long been considered the primary, if not sole, replicative DNA polymerase in eukaryotic cells. However, recent experiments have provided indirect evidence that a second DNA polymerase may play a role in DNA replication. To identify cellular proteins necessary for DNA synthesis in mammalian cells, we have been studying the cell-free system developed for the replication of simian virus 40 DNA. In this report, we present direct evidence that a second DNA polymerase is required in addition to DNA polymerase alpha-primase complex to obtain efficient replication of simian virus 40 origin-containing DNA. This DNA polymerase activity is not affected by monoclonal antibodies that inhibit the activity of DNA polymerase alpha and is relatively resistant to the inhibitor [N2-(p-n-butylphenyl)-9-(2-deoxy-beta-D-ribofuranosyl)guanine 5'-triphosphate]. Moreover, the activity of the polymerase is highly dependent upon the accessory protein, proliferating-cell nuclear antigen. These characteristics are consistent with the hypothesis that this second DNA polymerase is DNA polymerase delta.
