Table 1. The Protein Folding Variation Matrix (PFVM) for Human small ubiquitin-related modifier 1 (SUMO1_HUMAN) protein. Top section: the sequence of 101 of amino acids of SUMO1_HUMAN with numeric ruler. Section below sequence: the PFVM. The PFSC letters in each vertical column represent the local folding variation for 5 successive amino acids along sequence. The order of PFSC letters in each vertical column is ranked from higher to lower according the frequency numbers of folding shapes in PDB. The PFSC letters are marked by colors: red is for typical helix fold; blue for typical beta fold; pink and light blue for folds with partial helix or beta; black for irregular folds. Bottom section showed the disorder determined by PDB.
