| Abstract | The water-oxidation complex of Photosystem II (PS II) contains a heteronuclear cluster of 4 Mn atoms and a Ca atom. Ligands to the metal cluster involve bridging O atoms, and O and N atoms from amino acid side-chains of the D1 polypeptide of PS II, with likely additional contributions from water and CP43. Although moderate resolution X-ray diffraction-based structures of PS II have been reported recently, and the location of the Mn4Ca cluster has been identified, the structures are not resolved at the atomic level. X-ray absorption (XAS), emission (XES), resonant inelastic X-ray scattering (RIXS) and extended X-ray absorption fine structure (EXAFS) provide independent and potentially highly accurate sources of structural and oxidation-state information. When combined with polarized X-ray studies of oriented membranes or single-crystals of PS II, a more detailed picture of the cluster and its disposition in PS II is obtained. |

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.
