BSL RDHV predicted protein structures. (A) Structural analysis of the BSL RDHV capsid protein: The predicted structure for residues 156–302 of the BSL RDHV capsid protein monomer ORF is overlaid on the Tomato Bushy Stunt Virus (PDB ID: 2TBV) and Melon Necrotic Spot Virus (PDB ID: 2ZAH) capsid proteins (latter two are not shown). The predicted BSL RDHV capsid is color-coded by the “Qres” dimensional structure-fitting parameter score, by BLOSUM80, and by percent amino acid sequence identity. (B) Structural analysis of the BSL RDHV replicase catalytic core: The predicted BSL RDHV Rep nuclease domain structure (colored by Qres) threaded onto PCV2 Rep (PDB ID: 2HW0) in silver. The conserved active-site tyrosine is shown in yellow.
