|
On the one side, both amino acids are polar, but on the other side, His is positively charged, while Asp is negatively charged, which is an essential difference between these both amino acids. Therefore it is very likely, that this change causes big changes in the structure of the protein and the protein therefore will probably not work any longer. Furthermore, the structure of the two amino acids is very different, because of the aromatic ring of the His.

SIFT Prediction
SIFT Matrix:
Each entry contains the score at a particular position (row) for an amino acid substitution (column). Substitutions predicted to be intolerant are highlighted in red.
SIFT Table
Threshold for intolerance is 0.05.
Amino acid color code: nonpolar, uncharged polar, basic, acidic.
Capital letters indicate amino acids appearing in the alignment, lower case letters result from prediction.
