ApGlV2 capsid proteins. (A) The predicted structures of ApGlV2 (AGV) and tobacco necrosis virus (TNV) capsid proteins are similar. Homology modeling of tertiary protein structures of viral capsid protein for ApGlV2 and TNV (PBD:1C8N). Merge shows superimposed images of the two predicted CP structures with signature jelly-roll-like symmetric antiparallel β sheets. The images were generated using the LOMETS server. (B) Identification of ApGlV2 structural proteins. Purified virions (V; ~5 µg) were subjected to sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) (15% gel) and bands cut from the Coomassie brilliant blue-stained gel. The seven bands (1–7) were isolated for peptide sequencing. M, molecular mass markers.
