| Abstract | Sepiapterin reductase (7,8-dihydrobiopterin: NADP+ oxidoreductase, EC 1.1.1.153) catalyzes the terminal step in the biosynthetic pathway for tetrahydrobiopterin, the cofactor necessary for aromatic amino acid hydroxylation. We report here the isolation of a cDNA clone for rat liver sepiapterin reductase. The cDNA has been excised from a lambda vector and the DNA sequence was determined. The insert contains the coding sequence for at least 95% of the rat enzyme and is fused to the Escherichia coli beta-galactosidase N-terminal segment and the lac promoter. The N-terminal region of the clone contains an extraordinarily high G + C content. The amino acid sequence deduced from the clone is in agreement with the size and composition of the enzyme and was matched to several tryptic peptide sequences. The enzyme encoded by the cDNA insert was shown to have sepiapterin reductase activity after expression in E. coli. Structural similarities were identified between this protein and several enzymes that should contain similar nucleotide and pteridine binding sites. |

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.
