This application provides a visual
and pedagogical tool to understand the Ramachandran basin of different
residues. The library is generated by culling a library of
non-redundant X-ray structures from the PDB. The following
libraries are described in more detail in our work

(Biochemistry,
2005):
| Entire PDB |
A library of 2020 chains (X-ray structure; n > 20 residues, homology < 25%, R < 0.3, Resol. > 2Å |
| PDB- helix & sheet | From the "Entire PDB" library by
removing helices and
sheet as defined
by DSSP. |
| PDB- helix, sheet and turns |
From the "Entire PDB" library by removing helices, sheet and turns as defined by DSSP. |
| Coil Library |
Filtering for fragments smaller than 4 residues and by removing the end residues. |
