| Abstract | The herpes simplex virus type 1 protease and its substrate, ICP35, are involved in the assembly of viral capsids. Both proteins are encoded by a single open reading frame from overlapping mRNAs. The protease is autoproteolytically processed at two sites. The protease cleaves itself at the C-terminal site (maturation site) and also cleaves ICP35 at an identical site, releasing a 25-amino-acid (aa) peptide from each protein. To determine whether these 25 aa play a role in capsid assembly, we constructed a mutant virus expressing only Prb, the protease without the C-terminal 25 aa. Phenotypic analysis of the Prb virus in the presence and absence of ICP35 shows the following: (i) Prb retains the functional activity of the wild-type protease which supports virus growth in the presence of ICP35; (ii) in contrast to the ICP35 null mutant delta ICP35 virus, the Prb virus fails to grow in the absence of ICP35; and (iii) trans-complementation experiments indicated that full-length ICP35 (ICP35 c,d), but not the cleaved form (ICP35 e,f), complements the growth of the Prb virus. The most striking phenotype of the Prb virus is that only unsealed aberrant capsid structures are observed by electron microscopy in mutant-infected Vero cells. Our results demonstrate that the growth of herpes simplex virus type 1 requires the C-terminal 25 aa of either the protease or its substrate, ICP35, and that the C-terminal 25 aa are involved in the formation of sealed capsids. |

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.
