Histogram of the 86-element data set. Due to the RAM memory limits the protein number 55 in the 86-element data set list (PDB structures 2NGR and 1KZ7) was not included. The results are reported for the 85-element data set. The horizontal axis is the percentage of correct prediction of residues. The vertical axis is the number of proteins. The number of proteins with predicted pockets including more than half of the active site residues is 66 proteins (78% of the data set). Overlap threshold between pockets is 0.8.
