| Abstract | The eukaryotic DNA sliding clamp that keeps DNA polymerase engaged at a replication fork, called proliferating cell nuclear antigen (PCNA), is loaded onto the 3' ends of primer DNA through its interaction with a heteropentameric protein complex called replication factor C (RFC). The ATPase activity of RFC is necessary for formation of a functional PCNA clamp. In the present study, the sensitivity of RFC to partial proteolysis is used to show that addition of ATP, ATPgammaS, or ADP induces different structural changes in RFC. Direct observation by electron microscopy reveals that RFC has a closed two-finger structure called the U form in the absence of ATP. This is converted into a more open C form on addition of ATP. In contrast, the structural changes induced by ATPgammaS or ADP are limited. These results suggest that RFC adapts on opened configuration intermediately after ATP hydrolysis. We further observe that PCNA is held between the two fingers of RFC and propose that the RFC structure change we observe during ATP hydrolysis causes the attached PCNA to form its active ring-like clamp on DNA. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
