Example of a Heavy Elements Table (HET). The Heavy Elements Table (HET) obtained by applying the 3D profile method to the set of structurally aligned TP structures corresponding to the PROSITE AA_TRNA_LIGASE_II_2 pattern. Only the first representative lines of the HET are reported. Capital letters indicate the residue type in one-letter code while the number corresponds to the residue number in the PDB file. The 'v' symbol indicates a lacking residue in a cell. Residues belonging to the AA_TRNA_LIGASE_II_2 PROSITE pattern are underlined. The number at the beginning of each line is the profile score of the corresponding cell and the letter represents the consensus amino acid in that cell.
