| Abstract | The molecular conformation of peptide fragment 105-115 of transthyretin, TTR(105-115), previously shown to form amyloid fibrils in vitro, has been determined by magic-angle spinning solid-state NMR spectroscopy. 13C and 15N linewidth measurements indicate that TTR(105-115) forms a highly ordered structure with each amino acid in a unique environment. 2D 13C-13C and 15N-13C-13C chemical shift correlation experiments, performed on three fibril samples uniformly 13C,15N-labeled in consecutive stretches of 4 aa, allowed the complete sequence-specific backbone and side-chain 13C and 15N resonance assignments to be obtained for residues 105-114. Analysis of the 15N, 13CO, 13Calpha, and 13Cbeta chemical shifts allowed quantitative predictions to be made for the backbone torsion angles phi and psi. Furthermore, four backbone 13C-15N distances were determined in two selectively 13C,15N-labeled fibril samples by using rotational-echo double-resonance NMR. The results show that TTR(105-115) adopts an extended beta-strand conformation that is similar to that found in the native protein except for substantial differences in the vicinity of the proline residue. |

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.
