| Abstract | In this paper we propose a new algorithm to predict the phosphorylation site specificities of 478 human protein kinases based on the primary structures of the catalytic domains of these enzymes. Existing methods deduce the specificity of a protein kinase through the alignment of the amino acid sequences of phospho-sites targeted by the kinase to generate a consensus sequence or they use machine learning models for recognition. However, for most protein kinases few if any substrates have been experimentally identified by protein sequencing and mass spectrometry. In this work, we used mutual information from a training set of over 200 protein kinases consensus phospho-site sequences and predicted amino acid interactions between kinases and their substrate phospho-sites to generate position-specific scoring matrices (PSSM). The results demonstrate that using our algorithm, knowledge of the primary amino acid sequence of the catalytic domain of these kinases is sufficient to predict their phosphorylation sites specificities and their PSSM matrices. |

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.
