Abstract
En 中文
The Superimpose webserver performs structural similarity searches with a preference towards 3D structure-based methods. Similarities can be detected between small molecules (e. g. drugs), parts of large structures (e. g. binding sites of proteins) and entire proteins. For this purpose, a number of algorithms were implemented and various databases are provided. Superimpose ' assists the user regarding the selection of a suitable combination of algorithm and database. After the computation on our server infrastructure, a visual assessment of the results is provided. The structure-based in silico screening for similar drug-like compounds enables the detection of scaffold-hoppers with putatively similar effects. The possibility to find similar binding sites can be of special interest in the functional analysis of proteins. The search for structurally similar proteins allows the detection of similar folds with different backbone topology. The Superimpose ' server is available at: http://bioinformatics.charite.de/superimpose.
