| Abstract | Members of the serpin (serine protease inhibitor) superfamily have been identified in higher multicellular eukaryotes, as well as in bacteria, although examination of available genome sequences has indicated that homologs of the bacterial serpin-encoding gene (ser) are not widely distributed. In members of the genus Bifidobacterium this gene appears to be present in at least 5, and perhaps up to 9, of the 30 species tested. Moreover, phylogenetic analysis using available bacterial and eukaryotic serpin sequences revealed that bifidobacteria produce serpins that form a separate clade. We characterized the ser 210B locus of Bifidobacterium breve 210B, which encompasses a number of genes whose deduced protein products display significant similarity to proteins encoded by corresponding loci found in several other bifidobacteria. Northern hybridization, primer extension, microarray, reverse transcription-PCR (RT-PCR), and quantitative real-time PCR (qRT-PCR) analyses revealed that a 3.5-kb polycistronic mRNA encompassing the ser 210B operon with a single transcriptional start site is strongly induced following treatment of B. breve 210B cultures with some proteases. Interestingly, transcription of other bifidobacterial ser homologs appears to be triggered by different proteases. |

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.
