Figure 5
Individual Ramachandran plots for each of the 20 amino acids (All includes all 20 amino acids). Notice that most amino acids have two distinct maxima in the β-sheet region (upper left quadrant). Asp and Asn have the most complicated plots after Gly. This reflects their role in terminating α-helices and β-sheets. The two amino acids with highest preference for β-sheets, Ile and Val, have very similar Ramachandran plots. The plots of the three large hydrophobic amino acids Phe, Tyr and Trp look alike.
