Structure of the RRV nucleocapsid core. (a) Placement of the crystallographic SCP dimer C1 structure (yellow) into the observed electron density (blue). Neither the A1C1 nor the B1D2 dimers fit into the observed density. (b) In contrast with (a), the SCP monomer (yellow) fits into the RRV nucleocapsid density (blue) quite well. In agreement with cross-linking results, the Lys250 residues (denoted by asterisks) on adjacent capsomeres are ∼12 Å apart. [Reprinted by permission from Cheng et al. (1995), Cell, 80, 621–630.
