Myoglobin (left) is mainly alpha helical (see arrow 1); pepsin. (right) has beta sheets (see region of arrow 2)  for a specific subtype of α-helix. Such a graph is called a Ramachandran plot, shown below. While keeping track of dihedral angles in a protein may seem  Rotation about the amide bond. Ramachandran plots and regular structure.

a) alpha helix The alpha-helices and beta-sheets that form when the same phi/psi combination are repeated are particularly suited to providing hydrogen bonding opportunities   Aug 4, 2016 (b) Regular protein secondary structures, such as α-helices and β-sheets, correspond to single diffuse regions on a plot drawn in terms of ϕ and  142. 10.

These rotations are represented by the torsion angles phi and psi, respectively. G N Ramachandran used computer models of small polypeptides to systematically vary phi and psi with the objective of finding stable conformations.

Denna underdomän består huvudsakligen av ett kluster av a-helixer (α1-9) ganska högt α-spiralinnehåll (73%), och därför heter vi detta underdomän som en helixrik domän (HRD).

The Ramachandran Plot. In a polypeptide the main chain N-Calpha and Calpha-C bonds relatively are free to rotate. These rotations are represented by the torsion angles phi and psi, respectively. G N Ramachandran used computer models of small polypeptides to systematically vary phi and psi with the objective of finding stable conformations.
