| Abstract | Antibodies (anti-83 and anti-93) against the cellulose synthase complex from A. xylinum ATCC 53582 have been employed to study the evolutionary conservation of this enzyme complex among various A. xylinum strains, selected species of other cellulose- producing bacteria, algae, and vascular plants. Of the 18 A. xylinum strains examined, the 83 Kd polypeptide clearly is detected only in 4 strains while the 93 Kd polypeptide is observed in all 18 strains. Assuming that the revised acsAB gene (Saxena et al., 1994) encoding the 83 and 93 Kd polypeptides as a single polypeptide holds true for all A. xylinum strains, it is proposed that the cellulose synthase is conserved in A. xylinum but with varying degrees of homology. An unknown regulatory mechanism causing the degradation of the 83 Kd polypeptide in response to agitated culturing conditions has been suggested to explain the absence of the 83 Kd polypeptide in most of the Acetobacter strains examined. A. xylinum cellulose synthase appears to be conserved in phylogenetically related Rhizobium and Agrobacterium species, but not in algae and plants. |

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.
