Table 5. The PFVM of SUMO1_HUMAN embracing folding conformations of protein with known 3D structures. Top section: the sequence (21-84) of SUMO1_HUMAN protein with numeric ruler. Middle section: the 17 PSCF strings for conformations of 7 known 3D structures of SUMO1_HUMAN. Seven of structures are available in PDB: 1A5R is NMR data with 10 models; 3KYD, 1WYW, 1Y8R, 2PE6, 3KYC and 2BF8 are crystal X-ray diffraction data with one chain respectively and 1Y8R with two chains. The all PFSC letters of 1A5R-01 is first marked by yellow color. Other PFSC letters in same column for these given structures are marked by yellow color if they differ from 1A5R-01. Bottom section: the local folding variation with PFSC letters for PFVM of SUMO1_HUMAN protein. The PFVM of SUMO1_HUMAN protein. The PFSC letters in each column in PFVM are highlighted by yellow color if the corresponding local folding shapes for 5 successive amino acids in given 3D structures are yellow. 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.
