Welcome to the CNAnalysis Web Interface http://www.cnanalysis.de

Constraint Network Analysis (CNAnalysis) is a graph theory-based rigidity analysis approach that analyzes global and local flexibility and rigidity characteristics of proteins by carrying out thermal unfolding simulations. The approach has been used to predict the thermostability of proteins and to identify structural weak spots, i.e., residues that upon mutation would improve a protein's thermostability. Furthermore, the approach can also be applied in other areas of computational biomolecular research, e.g., for linking biomolecular flexibility and function and for investigating changes of biomolecular flexibility due to complex formation.
