Presentation of flexible-meccano
The program was originally developed to generate ensembles of realistic atomic models that are compatible with biophysical data measured using NMR and SAXS. flexible-meccano randomly samples amino-acid-specific backbone dihedral angle φ/ψ propensities derived from non-secondary structural elements of high-resolution X-ray crystallographic structures,and thereby assembles a conformational ensemble from which experimental values can be calculated. Amino-acid specific hard-sphere steric clashes are used to provide a physically reasonable model of repulsive interatomic forces, and no attractive forces are explicitly used. The simplicity of the model allows for highly efficient structure ensemble assembly (100,000 structures of a 100 amino acid protein can be created in 30 minutes on a single processor). It has now been entirely rewritten, updated and interfaced to include the following NMR calculations:
Two short movies presenting the main functionalities are available :
The program is delivered with example protocols and data and is fully documented. It has been compiled for the following platforms :
