I version of ESCET working in a pairwise fashion on different conformation of the same structure or structures of similar proteins with different sequences is also available as a web-server. The algorithm is called RAPIDO and you can find it here: webapps.embl-hamburg.de/rapido And is described i

This sounds like a job for a DDM (difference-distance matrix). This method can detect very subtle conformational changes between a pair of protein structures without performing a structural alignment. Once the areas of change have been identified a traditional alignment can be performed using the

Dear Crystallographers, I am sure that most here have dealt with the issue, when making superpositions of conformationally-different structures, of which regions to align as references and which to call "mobile." Conformational changes can range from very local (e.g., unwinding of a helix) to v
