Figure 9
Electrostatic surfaces of the XepA pentamer calculated using CCP4mg (McNicholas et al., 2011  ): red, −0.10 V e−1; white, 0.00 V e−1; blue, 0.10 V e−1. (a) View of the N-terminal disc, which is mostly positively charged. Acetate ions and glycerol molecules depicted in CPK representation (yellow) bind predominantly in the tube region. (b) View of the C-terminal disc, which shows a prevalently negatively charged surface. |
