Nest geometry. (a) For RL nests in the CSD, angle φi is plotted against ψi and angle φi + 1 is plotted against ψi + 1. (b) For LR nests in the CSD, angle φi is plotted against angle ψi and angle φi + 1 is plotted against angle ψi + 1. (c) For both RL and LR nests in the CSD the torsion angles H1—N1—N2—H2 and H2—N2—N3—H3 are plotted against each other. The numbers 1 and 2 and 3 represent nest residues i, i + 1 and i + 2. N and H are main-chain atoms. (d) For RL and LR nests in the CSD the N—N—N angle is plotted against the H1—N1—N2—H2 angle. |
