Predicting novel protein folds by using FRAGFOLD.

The results of applying a fragment-based protein tertiary structure prediction method to the prediction of 8 CASP4 targets are described. The method is based on the assembly of supersecondary structural fragments taken from highly resolved protein structures using a simulated annealing algorithm. Despite the significant degree of success in this case, there is clearly much more developmental work required before predictions with the accuracy of a good homology model, or even a good fold recognition model, can be made with use of this kind of approach.
