Figure 3. Charge distribution in E3_19 and E3_5. E3_19 is depicted on the left, E3_5 is depicted on the right. (a) Negative charges in the -turn regions. Negatively charged residues are depicted in stick mode in red on the backbones in ribbons. For completeness, Asp122 of E3_19 is also shown. (b) Positively charged residues (stick mode in blue) in the first three repeats of E3_19 and the first and fourth repeat of E3_5, respectively, are depicted on the backbones in ribbons. (c) Surface representations of the electrostatic potential of E3_19 and E3_5 (red = -0.5, white = 0, blue = +0.5). For orientation identically positioned ribbon representations are depicted on the left of each surface representation.
