Details The structures are based on a set of 35 to 60 backbone-backbone, backbone-side chain and side chain-side chain distance restraints. The phi angle for the non glycine D-residues was constrained between 0 and 175. A distance dependent dielectric constant equal to 4r was applied. The net electric charges were decreased, while those of the N and C terminal charged groups were neglected.
