Improved efficiency of protein structure calculations from NMR data using the program DIANA with redundant dihedral angle constraints

SummaryA new strategy for NMR structure calculations of proteins with the variable target function method (Braun, W. and Go, N. (1985)J. Mol. Biol.,186, 611) is described, which makes use of redundant dihedral angle constraints (REDAC) derived from preliminary calculations of the complete structure. The REDAC approach reduces the computation time for obtaining a group of acceptable conformers with the program DIANA 5-100-fold, depending on the complexity of the protein structure, and retains good sampling of conformation space.
