The structural features that define an alpha-helix are: the relative locations of the Se hela listan på proteopedia.org 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. Focusing on the classically defined beta-region, this plot reveals a natural break into four regions: The helical form models could be built with varying degrees of twist, but one model fit the atomic dimensions especially well: The Ramachandran plot is a foundational concept used in biochemistry courses to describe the basic elements of protein structure, but in most cases the approach is based on a decades old view of secondary structure types summarized in the IUPAC nomenclature from A special way for plotting protein torsion angles was introduced by Ramachandran and co-authors and since then is called the Ramachandran plot. 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. In 1951, Pauling, Robert Corey and Herman Branson published their descriptions of the alpha helix and beta sheet motifs. Ramachandran wanted to continue this work, and chose to study the structure of collagen first. 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.

The protein is in the shape of a cylinder, comprising 11 strands of beta-sheet with an alpha-helix inside and short helical segments on the ends of the cylinder.

The Ramachandran plot of this peptide has points clustered about the values of φ= -57 o and ψ= -47 o which are the average values for α-helices. In 1951, Pauling, Robert Corey and Herman Branson published their descriptions of the alpha helix and beta sheet motifs. Ramachandran wanted to continue this work, and chose to study the structure of collagen first. Collagen is protein found abundantly in the human body: it makes up the bulk of our skin, cartilage and connective tissues.
