Structural patterns in globular proteins
@article{Levitt1976StructuralPI, title={Structural patterns in globular proteins}, author={Michael Levitt and Cyrus Chothia}, journal={Nature}, year={1976}, volume={261}, pages={552-558} }
A simple diagrammatic representation has been used to show the arrangement of α helices and β sheets in 31 globular proteins, which are classified into four clearly separated classes. The observed arrangements are significantly non-random in that pieces of secondary structure adjacent in sequence along the polypeptide chain are also often in contact in three dimensions.

The topological connectivities of β-pleated sheets in the known protein structures are systematically surveyed for regularly occurring features and suggest that striking topological similarities between different proteins can readily happen by chance.
Asymmetry in protein structures.
- ChemistryCiba Foundation symposium

The asymmetry of L-amino acids determines the asymmetrical features of alpha-helices and beta-sheets, and certain topological features of the paths followed by polypeptide chains through structures determine the three-dimensional structure of proteins.
Analysis and prediction of protein β-sheet structures by a combinatorial approach
