Summary
Globular protein shape anisotropy was analyzed using geometrical parameters. Secondary structures significantly influence the final protein shape design.
Area of Science:
- Biophysics
- Structural Biology
- Protein Science
Background:
- Globular proteins exhibit complex three-dimensional structures.
