| Abstract | Cells of Bacillus subtilis 168 (trpC2) growing and sporulating in a single chemically defined medium carried out intracellular protein degradation and increased their levels of intracellular serine protease-1 in a manner very similar to what had previously been reported for cells sporulating in nutrient broth. The results were interpreted to mean that these processes are intrinsic to sporulation rather than medium dependent. To determine the cause of these increases in specific activity of proteinases, we purified the protease, prepared rabbit immunoglobulins directed against it, and monitored changes in protease antigen levels by performing rocket immunoelectrophoresis. In cells sporulating in nutrient broth, the protease antigen levels increased about 7-fold, whereas the specific activity increased about 150-fold, for an activation of about 20-fold. In cells sporulating in the single chemically defined sporulation medium, the protease antigen increased about 10-fold, whereas the specific activity increased at least 400-fold, for an activation of about 40-fold. These results were interpreted to mean that a posttranslational event activated the protease in vivo; a previously described endogenous proteinase inhibitor was confirmed to be present in the strain used. Chloramphenicol added to the cultures inhibited both the increases in antigen levels and in the specific activity of the proteinase. |

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.
