Stability – Aliphatic Index

The Stability – Aliphatic Index track (Gasteiger et al. 2005) predicts regional stability by calculating the relative volume occupied by aliphatic side chains. This is a positive indicator of globular protein thermostability. This method is only available for amino acid selections. Detailed information about this method is available on the ExPASY website.

To apply this track to the sequence:

In the Tracks panel, expand Stability and check the box next to Aliphatic Index. The track will now be visible in the Sequences view.

To edit track options:

Select the track in the Tracks panel. Open the Track Options section, which appears as follows:

• Residues to average – number of residues to be averaged when constructing each point in the plot. The default is 9.
