Grantham difference
WebAlign-GVGD is a freely available, web-based program that combines the biophysical characteristics of amino acids and protein multiple sequence alignments to predict where missense substitutions in genes of interest fall in a spectrum from enriched delterious to enriched neutral. Align-GVGD is an extension of the original Grantham difference to ... Grantham's distance depends on three properties: composition, polarity and molecular volume. [4] Distance difference D for each pair of amino acid i and j is calculated as: D i j = [ α ( c i − c j ) 2 + β ( p i − p j ) 2 + γ ( v i − v j ) 2 ] 1 2 {\displaystyle D_{ij}=[\alpha (c_{i}-c_{j})^{2}+\beta (p_{i} … See more Amino acid replacement is a change from one amino acid to a different amino acid in a protein due to point mutation in the corresponding DNA sequence. It is caused by nonsynonymous missense mutation which changes the … See more Amino acids can also be classified according to how many different amino acids they can be exchanged by through single nucleotide substitution. • Typical … See more Evolution of proteins is slower than DNA since only nonsynonymous mutations in DNA can result in amino acid replacements. Most … See more Not all amino acid replacements have the same effect on function or structure of protein. The magnitude of this process may vary … See more Physicochemical distance is a measure that assesses the difference between replaced amino acids. The value of distance is based … See more Some amino acids are more likely to be replaced. One of the factors that influences this tendency is physicochemical distance. Example of a measure of amino acid can be Graur's Stability Index. The assumption of this measure is that the … See more
