TADOSS: computational estimation of tandem domain swap stability.


ABSTRACT: Summary:Proteins with highly similar tandem domains have shown an increased propensity for misfolding and aggregation. Several molecular explanations have been put forward, such as swapping of adjacent domains, but there is a lack of computational tools to systematically analyze them. We present the TAndem DOmain Swap Stability predictor (TADOSS), a method to computationally estimate the stability of tandem domain swapped conformations from the structures of single domains, based on previous coarse-grained simulation studies. The tool is able to discriminate domains susceptible to domain swapping and to identify structural regions with high propensity to form hinge loops. TADOSS is a scalable method and suitable for large scale analyses. Availability:Source code and documentation are freely available under an MIT license on GitHub at https://github.com/lafita/tadoss. Supplementary information:Supplementary data available at Bioinformatics online.
