Ramachandran Plot. Ramachandran plots serve as indirect verification tool of the stereochemistry and geometry of the complex by establishing that none of the geometries are in the forbidden electrostatically unfavored regions of the plot. From: Viral Polymerases, 2019. Related terms: Alpha Helix; Peptide; Protein Secondary Structure; Proline; Dihedral Angle

It is used to show the ranges of angles that are permissible and the main types of structure adopted by a polypeptide chain (for example, α helix, β sheet). Revisiting the Ramachandran plot: hard-sphere repulsion, electrostatics, and H-bonding in the alpha-helix. Bosco K Ho, Annick Thomas, Robert Brasseur Centre de Biophysique Moleculaire Numerique (CBMN), B-5030 Gembloux, Belgium. [email protected] Notably, in the Ramachandran plot the β-strand region covers a greater conformational space than the α-helix regions 62 , which involves steric, electrostatic and hydrogen-bonding interactions 63. BCH210H1 Lecture Notes - Lecture 4: Polyproline Helix, Alpha Helix, Ramachandran Plot The Ramachandran plot shows that the secondary structure of the CRY1 protein is primarily a right-handed alpha helix with little to no steric overlap.

Jan 4, 2011 Bifurcated hydrogen bonds form once again as the conformation shifts from β- turns to α-helix but then resolve yet again into the familiar i → i - 4  Jan 4, 2011 The imposition of steric and hydrogen-bonding constraints was sufficient to deduce the struc- tures of α-helix and β-sheet once Pauling had  Ramachandran Plot. Bond Angles. Primary Angles of Stability Alpha Helix. Beta Strands / Beta Helix. Reverse turns (5 types).

2017-12-22 Despite the fact that, based on the Ramachandran plot, both right-handed and left-handed alpha helices are among the permitted conformations, the right-handed alpha helix is energetically more favorable because of fewer steric clashes between the side chains and the main chain.

Protein secondary structure: Ramachandran plot. Myoglobin (left) is mainly alpha helical (see arrow 1); pepsin. (right) has beta sheets (see region of arrow 2) 

Collagen is protein found abundantly in the human body: it makes up the bulk of our skin, cartilage and connective tissues. Now that we know how a Ramachandran plot is made, we can rephrase the question as "Why are the φ and ψ values for alpha helices and beta sheets so restricted?" Alpha helices: The formation of an alpha helix requires the protein backbone to loop around very sharply on top of itself.

Looking down on the α-carbon from the direction of the hydrogen atom, the so that the Ramachandran plot (with 0°,0° at the bottom left) had the α-helix in the

A Ramachandran plot generated from human PCNA, a trimeric DNA clamp protein that contains both β-sheet and α-helix (PDB ID 1AXC). The red, brown, and yellow regions represent the favored, allowed, and "generously allowed" regions as defined by ProCheck Ramachandran plots serve as indirect verification tool of the stereochemistry and geometry of the complex by establishing that none of the geometries are in the forbidden electrostatically unfavored regions of the plot. From: Viral Polymerases, 2019 The Ramachandran plot provides a way to view the distribution of torsion angles in a protein structure and shows that the torsion angles corresponding to the two major secondary structure elements (α-helices and β-sheets) are clearly clustered within separate regions.
