Fig. 5. An example of protein tertiary structure.Uniprot database Many proteins are assembled in more than one polypeptide chain, known as protein subunits. In addition to the tertiary structure of the subunits, multiple-subunit proteins possess a quaternary structure, which is the three-d...
Protein secondary structure prediction is one of the most important and challenging problems in bioinformatics. Machine learning techniques have been applied to solve the problem and have gained substantial success in this research area. However there is

Combine this coloring with rocking the structure and you will have a good idea of how the linear primary sequence folds into the final tertiary structure. Select Cartoon and Structure. Now you can clearly see the position of the secondary structure elements. You can see the α-helices and how...
Circular dichroism spectroscopy is a widely used technique to analyze the secondary structure of proteins in solution. Predictive methods use the circular dichroism spectra from proteins of known tertiary structure to assess the secondary structure conte
Data sets, training/test folds and multiple alignments are identical to those used to train and test the ab initio secondary structure predictor Porter [19]. Template generation For each of the proteins in S2171 we search for structural templates in the PDB. We base our search on PDBFINDERII...
