Pysicochemical Properities

Leu	Phe	consequences
aliphatic, hydrophobic, neutral	aromatic, hydrophobic, neutral	Leu is an aliphatic amino acid, wheras Phe is an aromatic amino acid. This means, that Phe has an aromatic ring in its structure. But both amino acids are relatively big and so it is possible, that the exchange of this amino acids do not change the structure of the protein that much. Therefore, we suggest it is possible, that the protein will work.

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.
