Extended Data Fig. 9: Electrostatic potential of individual capsomeres of dArc1 and dArc2.
From: Structures of virus-like capsids formed by the Drosophila neuronal Arc proteins

a, As in Fig. 3, the surface is coloured with the electrostatic potential from -5 (red) to +5 kbT/e (blue). The dArc2 capsomeres are more electropositive than the dArc1 capsomeres. b, Close-ups showing that additional neutral-to-basic residue substitutions facilitate electrostatic charge differences in the capsid interior.
