![]() ![]() Many more scales have been published in the literature throughout the last three decades Many of the commonly used hydrophobicity scales are: Kyte-Doolittle scale, Engelman scale (GES scale), Eisenberg scale, Hopp-Woods scale, Cornette scale, Rose scale, and Janin scale. There are several hydrophobicity scales have been published for various uses. In hydrophobicity plot, the degree of hydrophobicity is taken from the hydrophobicity scale. The plot has amino acid sequence of a protein on its x-axis, and degree of hydrophobicity on its y-axis. It is used to characterize or identify possible structure or domains of a protein. At the central position of the window, the average hydrophobicity of the entire windows is plotted.Ī hydrophobicity plot is a quantitative analysis of the degree of hydrophobicity of amino acids of a protein. ![]() The hydrophobicity is calculated by sliding a fixed size window (of an odd number) over the protein sequence. Usually, these calculations are shown as a plot along the protein sequence, making it easy to identify the location of potential protein features. This can be membrane spanning regions, antigenic sites, exposed loops or buried residues. Calculation of hydrophobicity in proteins is important in identifying its various features. Hydrophobicity is the property of being water repellent, tending to repel and not absorb water. ![]()
