Figure 3. Improvement in model accuracy using NMR simulated sparse data.

Figure 3

(A) Improvement in terms of the GDT_TS score for all the CASP11 modeling targets for which sparse data were available. Scores for the best original model submitted in CASP (“unassisted”, blue), results obtained with CNS (green), and obtained by CASP participants (red) utilizing the sparse data are shown. For most targets, CASP data assisted results show a dramatic improvement in model accuracy. For example, for the first target, Ts814, GDT_TS improves from 16 to 70, corresponding to a change in Cα RMSD from 21.1 Å to 2.6 Å. Improvements using conventional CNS procedures are considerably smaller. (B) Best models obtained for CASP11 target T0777. Left: Best unassisted model (RMSD to the experimental structure is 14.7 Å); Center: Experimental structure; Right: Best model obtained with sparse data (3.7 Å RMSD).
