This slide shows an example of the "5-tile code" of an actual protein, transferase (1RKL).
Its amino acid sequence is given above and the 5-tile code is shown below.
The figure shows the structural features of the protein and spatial arrangement of the 5-tile codes, where small blue balls stand for 5-tile code "0", large yellow balls for "R", ...
As you see, "strand" corresponds to "0", "turn" corresponds to "R", ...
That is, "5-tile code" could capture local features of the protein precisely.
