Legend

For each protein the table shows its Protein Data Bank (PDB) code, Enzyme Classification (EC) number, size, number of sequences in the trace alignment, minimum percent sequence identity of the alignment evolutionary breadth (E=Eukaryota, B=Bacteria, A=Archaea, V=Viruses), and, for each of the 4 statistics, the %fraction of ranks with significant trace clusters that also have a significant overlap with the functional site. TCR=Total Connected Residues, LCO=Largest Cluster Overlap; AO=Average Overlap; HG=Hypergeometric Distribution. Functional sites are then shown in green, and finally Trace clusters are colored individually: red=largest, blue=second largest, etc. Single-residue clusters are black. Ligands are colored yellow/orange or blue if they are peptides. There are no ligands shown in the EC set.

To view a picture at a larger size, right-click (or hold-and-click) it and choose 'View Image'. Rotating animated images of these proteins will be made available each week in the Trace of the Week.

"NA" indicates that no significant ranks exist either for lack of sequence diversity (*), or because its size is too small (**) - see Madabushi et al., JMB 2002. In the case of 1bqk (***), the size of the largest cluster was significant, but the number of clusters was not (at the rank shown, there are 5 single-residue clusters in addition to the large cluster shown).
