Figure 4.

Helical wheel (a) and net diagrams (b) of magainin I [42]. Amino acids are indicated by their single-letter abbreviations and are categorized according to the following colors: polar basic (red), polar acidic (blue), polar uncharged (green), nonpolar (yellow). Both the wheel and net diagrams demonstrate the division of hydrophobic and hydrophilic components of the peptide. The helical wheel diagram was generated using online software called NetWheels [43] and the net diagram was made using Microsoft PowerPoint.
