Figure 3. Mechanistic explanation of surfactant properties of PhaPAh and hypothetical formation process of a PhaPAhtetramer.

Figure 3

(A) The amphiphilic surfaces of type I and II chains. Type I is found in chains A and D, and type II in chains B and C. All hydrophobic amino acid side chains are shown for both types. (B) The simulated process of tetramer formation via hydrophobic interaction. It begins from a dimer of chains A and D, chains C and B follow.
