| Abstract | The bovine papillomavirus type I transcriptional activator E2 is essential for replication of bovine papillomavirus DNA, yet most of the high-affinity binding sites for E2 are dispensable. Here we demonstrate an absolute requirement for a binding site for the E2 polypeptide as a cis-acting replication element, establishing that site-specific binding of E2 to the origin is a prerequisite for bovine papillomavirus replication in vivo. The position and distance of the E2 binding site relative to the other origin of replication components are flexible, but function at a distance requires high-affinity E2 binding sites. Thus, low-affinity binding sites function only when located close to the origin of replication, while activity at greater distances requires multimerized high-affinity E2 binding sites. The requirement for E2, although different in some respects, shows distinct similarities to what has been termed replication enhancers and may provide insight into the function of this class of DNA replication element. |

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.
