Supersecondary structures or motifs, are simple and frequent combinations of the secondary structure with a specific geometric arrangement. Supersecondary structures can also be considered as an intermediate between secondary and…
Helical net diagrams are used to represent the arrangement of side chains in α-helical regions of protein. Also you can say a separate representation that involves a hypothetical razor cut…
A helical wheel is a type of plot or visual representation used to illustrate the properties of alpha helices in proteins on a 360 degree map with respect to the side of the…
The Secondary structure of protein was first recognized by Corey and Pauling in 1951. They both observed that secondary structure of protein must accommodate the hydrogen bonding potential of the…
Primary Structure The primary structure of proteins refers to the linear sequence of its amino acid structural units. Linderstrom-Lang in 1951, first coined the term "primary structure". The primary structure sequence is determined by the nucleotide sequence…
Forces Stabilizing Protein Structure determines the native, folded structure of the protein means the native structure of protein is dictated by several factors like interactions with solvent molecules (normally water),…
Hydropathy Plot is also termed as Hydrophobicity (or hydrophilicity) plots. Hydropathy Plot are designed to display the distribution of polar and nonpolar residues along a protein sequence. This analysis has the…
Hydropathy index or Hydrophobicity index are values which can be define as the relative hydrophobicity of amino acid residues. Two of the most commonly used hydropathy index are incorporated into the hydropathy analysis: (i) Kyte-Doolitle (ii)…
The Ramachandran plot is a plot used to study proteins. The discussions made in the dihedral angles can be used to study the structure of protein and can be graphically…
Before going in detail of dihedral angles, we need to understand the conformation of peptide bond and its rigidity. Conformation of Peptide In the peptide bond, the π-electrons from the…
