Pysicochemical Properities

First of all, we explored the amino acid properties and compared them for the original and the mutated amino acid. Therefore we created the possible effect that the mutation could have on the protein.

Trp	TER	consequences
aromatic, polar, hydrophobic	TER	By this change, the protein is not complete, therefore it is not possible for the protein to fold and to function.

SNAP Prediction

No prediction available, because the protein ends here.

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.

PolyPhen2 Prediction

In this case the mutation is from Tryptophan to a stop codon. Therefore, we made no PolyPhen2 prediction, because it is clear that it will cause a damage of the 3D-structure of the protein. Furthermore, it will of course .....
