| Abstract | Understanding how an amino acid substitution affects a protein's structure is fundamental to advancing drug design and protein docking studies. Mutagenesis experiments on physical proteins provide a precise assessment of the effects of mutations, but they are time and cost prohibitive. Computational approaches for performing in silico amino acid substitutions are available, but they are not suited for generating large numbers of protein variants needed for high-throughput screening studies. We present ProMuteHT, a program for high throughput in silico generating user-specified sets of mutant protein structures with single or multiple amino acid substitutions. We combine our custom mutation algorithm with side chain homology modeling external libraries, and generate energetically feasible mutant structures. Our efficient command-line invocation syntax requires only a few arguments to specify large datasets of mutant structures. We achieve quick run-times due to our hybrid approach in which we limit the use of costly energy calculations when mutating from a large to a small amino acid. We compare our mutant structures with those generated by FoldX, and report faster run-times. We show that the mutants generated by ProMuteHT are of high quality, as determined via all-atom and mutated residue RMSD measurements for existing mutant structures in the PDB. |

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.
