Abstract

In an attempt to study the mechanism of initiation of adenovirus DNA replication, an assay was developed to investigate the pattern of DNA synthesis in early replicative intermediates of adenovirus DNA. By using wild-type virus-infected cells, it was possible to place the origin of adenovirus type 2 DNA replication within the terminal 350 to 500 base pairs from either of the two molecular termini. In addition, a variety of parameters characteristic of adenovirus DNA replication were compared with those obtained in a soluble nuclear extract competent for viral DNA replication. It was observed that in vitro DNA replication, which is dependent on the exogenously added viral DNA-protein complex as its optimal template, occurs in a manner apparently indistinguishable from the situation in virus-infected cells. This includes the presence of proteinaceous material on the molecular termini of newly initiated viral DNA.

摘要

为了研究腺病毒DNA复制起始的机制,开发了一种测定方法来研究腺病毒DNA早期复制中间体中的DNA合成模式。通过使用野生型病毒感染的细胞,有可能将腺病毒2型DNA复制的起始位点定位在两个分子末端中任一端的末端350至500个碱基对范围内。此外,将腺病毒DNA复制的各种特征参数与在能够进行病毒DNA复制的可溶性核提取物中获得的参数进行了比较。据观察,体外DNA复制依赖于外源添加的病毒DNA - 蛋白质复合物作为其最佳模板,其发生方式与病毒感染细胞中的情况明显无法区分。这包括新起始的病毒DNA分子末端存在蛋白质物质。
