Figure 2

Comparison of methods for secondary structure assignment. Example of 5 assignments for the ribosomal protein S15 from Bacillus Stearothermophilus (PDB code 1A32). The figure shows the amino acid sequence (AA), the secondary structure assignments by (DSSP), (STRIDE), (PSEA), (DEFINE), (PCURVE) with 'H' for the α-helix, 'E' for the β-strand and 'C' for the coil, (cons.) is a simple consensus with a star (*) if the five methods agree or a dot (.) if they do not, (PB) is the Protein Block assignment with ZZ for the extremities (not assigned, i.e., the PB is centered on the central residue).
