Outline of Final Research Achievements |
PCNA has a trimeric ring structure that encircles the DNA, and increases the processivity of the bound DNA polymerase by tethering it to the DNA. It is known now, that PCNA also interacts with multiple partners, such as DNA ligase and FEN, to control DNA replication, and works not only as the platform, but also as the conductor for the recruitment and release of these factors. However, the molecular architectures as well as the mechanism of the regulation of these replication factors are not known in detail. In order to investigate the switching mechanism between the replication factors in more detail, we studied the complex structures with two replication factors bound to one PCNA ring, by single particle analysis. We could successfully visualize the 3D structure of FEN-DNA ligase-PCNA-DNA complex, the intermediate state of Okazaki fragment maturation, and the handing over of the ds DNA strand from FEN to DNA ligase.
