| Abstract | The mechanism by which the 14-kDa fusion protein of vaccinia virus (VV) is anchored in the envelope of intracellular naked virions (INV) is not understood. In this investigation, we demonstrate that the 14-kDa protein interacts with another virus protein with an apparent molecular mass of 21 kDa. Microsequence analysis of the N terminus of the 21-kDa protein revealed that this protein is encoded by the VV A17L gene. The 21-kDa protein is processed from a 23-kDa precursor, by cleavage at amino acid position 16, at the consensus motif Ala-Gly-Ala, previously identified as a cleavage site for several VV structural proteins. The 21-kDa protein contains two large internal hydrophobic domains characteristic of membrane proteins. Pulse-chase analysis showed that within 1 h after synthesis, the 14-kDa protein forms a stable complex with the 21-kDa protein. Formation of the complex was not inhibited by rifampin, indicating that the interaction between these two proteins occurs prior to virion morphogenesis. Immunoprecipitation analysis of disrupted virions showed the presence of the 21-kDa protein in the viral particle. Release of the 14-kDa-21-kDa protein complex from INV required treatment with the nonionic detergent Nonidet P-40 and a reducing agent. The protein complex consisted of 14-kDa trimers and of 21-kDa dimers. Since the 14-kDa fusion protein lacks a signal sequence and a large hydrophobic domain characteristic of membrane proteins, our findings suggest that the 21-kDa protein serves to anchor the 14-kDa protein to the envelope of INV. |

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.
