Figure 5. Electrostatic zipper between E3 (green, monomer A; pink, monomer B) and E2BD (blue) of B. stearothermophilus. The side chains of Asp344 and Glu431 of monomer B of E3 adopt different conformations in the present complex structure to facilitate the formation of salt bridges with the binding domain. Side chains of Asp344 and Glu431 in the uncomplexed E3 structure are shown with thin bonds. Figure 5.
