Monomeric and tetrameric structure of the Groundnut ringspot virus (GRSV) nucleoprotein (N). a Cartoon representation of monomeric GRSV N with rainbow coloring from N- (blue) to C-terminus (red). b Electrostatic surface of the GRSV N with a positively charged groove in complex with RNA shown as yellow (carbons) and red (oxygens) sticks. Positive and negative charges are blue and red, respectively. c N-terminus interaction surface representation of four GRSV N monomers A, B, C, D shown in color pink, yellow, cyan and green, respectively. d C-terminus interaction surface representation of the GRSV N tetrameric ring. The RNA is shown in black sticks deeply bound inside the tetrameric ring. e Cartoon representation with the N-arm oligomerization interface showing interacting residues. The N-terminal arm is in pink and the globular region is in green. The intermolecular hydrogen bonds are shown as yellow dotted lines. f 180° rotation of Fig. 2e, C-arm oligomerization interface showing interacting residues. The C-terminal arm is in cyan and the globular region is in green
