- Abstract
- Nearly 20 percent of the packaged RNA in bean-pod
mottle virus (BPMV) binds to the capsid interior in a
symmetric fashion and is clearly visible in the electron
density map. The RNA displaying icosahedral symmetry is
single-stranded with well-defined polarity and
stereochemical properties. Interactions with protein are
dominated by nonbonding forces with few specific contacts.
The tertiary and quaternary structures of the BPMV capsid
proteins are similar to those observed in animal
picornaviruses, supporting the close relation between plant
comoviruses and animal picornaviruses established by
previous biological studies.
