Fig. 2From: An assessment of catalytic residue 3D ensembles for the prediction of enzyme functionOccurrence of enzymes from the six EC classes. The dark bars give the fraction of the enzymes in ENZ_SITES, the light bars their fraction in the PDB. On top of the bars, the ratio of the corresponding fraction values is printed. The value of 1.16 indicates that enzymes from EC class 1 are 16 % overrepresented in ENZ_SITES with respect to their occurrence in the PDBBack to article page
