| Abstract | A full-length cDNA sequence, encoding a novel endo-1,4-β-d-xylanase (AuXyn10A) of Aspergillus usamii, was obtained by using rapid amplification of cDNA ends (RACE) methods and cloned into the pUCm-T vector, followed by DNA sequencing. The cDNA gene, designated as Auxyn10A, is 1,235 bp in length harboring 5′- and 3′-non-encoding regions, as well as an ORF of 984 bp that encodes a 19-aa signal peptide, a 6-aa propeptide and a 302-aa mature peptide with a calculated MW of 32,756 Da. The AuXyn10A displays high similarity to the xylanases of Aspergillus niger, Aspergillus kawachii and Aspergillus niger, members of the glycoside hydrolase family 10. Its three-dimensional structure was predicted using http://swiss-model.expasy.org/on-line programs based on the crystal structure of Penicillium simplicissimum xylanase (1B30_A) from the family 10. The complete DNA gene was cloned from the genomic DNA of A. usamii using conventional PCR and hairpin structure-mediated PCR techniques. The DNA gene is 2,255 bp in length, containing a 510 bp of 5′-flanking promoter region and a 1,745 bp of downstream fragment that consists of ten exons and nine short introns ranging from 52 to 62 bp. |

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.
