SculptorCNS

Structure Calculation Using Long-range, Paramagnetic, Tensorial and Orientational Restraints

Presentation

We present a suite of programs, including functional representations of the following long-range structural restraints in the form of explicit hybrid potentials that are included in the total energy function of an energy minimization, restrained molecular dynamics or simulated annealling approach :

– Residual dipolar couplings
– Residual Chemical Shift Anisotropy
– Paramagnetic Residual Dipolar Couplings
– Paramagnetic Pseudocontact Shifts
– Curie-Dipole Cross Correlated Relaxation
– R2/R1 Auto-Relaxation Rates

Sculptor was specifically written to allow maximal flexibility in the development of conformational search algorithms using long-range structural restraints. As many of these interactions depend on second rank tensorial interactions (alignment tensors, magnetic susceptibility tensors or rotational diffusion tensors), particular attention is paid to the treatment of this kind of tensor in the program.

The program was originally interfaced in its initial format to the program Discover, and has now been entirely rewritten, updated to include the most recent developments of tensor-based constraints for NMR structure refinement, and interfaced to CNS version 1.2, a popular program for crystallographic and NMR structure determination. Sculptor-CNS is distributed free of charge to academic users.

The program is delivered with example protocols and data and is fully documented.
