| Abstract | Due to its high abundance, the D-xylose fraction of lignocellulose provides a promising resource for production of various chemicals. Examples of efficient utilization of d-xylose are nevertheless rare, mainly due to the lack of enzymes with suitable properties for biotechnological applications. The genus Arthrobacter, which occupies an ecological niche rich in lignocellulosic materials and containing species with high resistance and tolerance to environmental factors, is a very suitable candidate for finding D-xylose-degrading enzymes with new properties. In this work, the presence of the pAO1 megaplasmid in cells of Arthrobacter nicotinovorans was directly linked to the ability of this microorganism to ferment D-xylose and to sustain longer log growth. Three pAO1 genes (orf32, orf39, orf40) putatively involved in degradation of xylose were identified and cloned, and the corresponding proteins purified and characterized. ORF40 was shown to be a homotetrameric NADP(+)/NAD(+) sugar dehydrogenase with a strong preference for d-xylose; ORF39 is a monomeric aldehyde dehydrogenase with wide substrate specificity and ORF32 is a constitutive expressed transcription factor putatively involved in control of the entire catabolic pathway. Based on analogies with other pentose degradation pathways, a putative xylose oxidative pathway similar to the Weimberg pathway is postulated. |

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.
