Figure 3.7: Ribose binding protein (open) Morph ID: f924994-9791 PDB ID: 1drj Hinge Atlas Gold hinges: 103,104,235,236 b. The single-cut predictors correctly suggest the hinge at residue 103, but less clearly at residue 235. Several false positives can also be seen, at residue 135 and around residue 50. c. The 2-cut predictor yielded the correct result, as indicated by the minimum circled in green. 153
