Hydrophobicity plot
Displaying the hydrophobicity for a protein sequence in a plot is done in the following way:
select a protein sequence in Navigation Area |
Toolbox in the Menu Bar | Protein Analysis (
)| Create Hydrophobicity Plot (
)
This opens a dialog. The first step allows you to add or remove sequences. Clicking Next takes you through to Step 2, which is displayed in figure 16.11.
Figure 16.11: Step two in the Hydrophobicity Plot allows you to choose hydrophobicity scale and
the window size.
The Window size is the width of the window where the hydrophobicity is calculated. The wider the window, the less volatile the graph. You can chose from a number of hydrophobicity scales which are further explained in Bioinformatics explained: Protein hydrophobicity Click Next if you wish to adjust how to handle the results. If not, click Finish. The result can be seen in figure 16.12.
