| Abstract | We have previously reported the detection of two unusual nucleotides, pdJ and pdV, in the DNA of Trypanosoma brucei (Gommers-Ampt et al., 1991). pdJ was found to be a novel nucleotide and is possibly involved in the regulation of variant specific surface antigen gene expression in trypanosomes. Recent evidence suggests that V could be a precursor of J, making V a key compound in the study of the biosynthesis and function of J. We have therefore determined the structure of V and here we present proof that V is HOMeU. The identity is based on a detailed comparison of dV(p) with authentic HOMedU(p), showing: I) co-migration in three different liquid chromatography analyses II) identical UV absorbance characteristics III) identical behavior in acetyl-pentafluorobenzyl derivatization and subsequent Gas chromatography/Mass spectrometry (GC/MS). The GC/MS technique has not been used before to analyse HOMedU purified from biological material. Because of its high sensitivity, it may also be useful for the detection of the low amounts of HOMedU resulting from oxidative damage of DNA. |

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.
