| Abstract | Gene 28 of Bacillus subtilis bacteriophage SPO1 codes for a regulatory protein, a sigma factor known as sigma gp28, that binds to the bacterial core RNA polymerase to direct the recognition of phage middle gene promoters. middle promoters exhibit distinctive and conserved nucleotide sequences in two regions centered about 10 and 35 base pairs upstream from the start point of mRNA synthesis. Here we report the cloning of gene 28 and its complete nucleotide sequence. We infer that sigma gp28 is a 25,707-dalton protein of 220 amino acids. Neither the nucleotide sequence of gene 28 nor the inferred amino acid sequence of sigma gp28 exhibits extensive homology to the gene or protein sequence of Escherichia coli sigma factor. |

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.
