Abstract
The outer capsid protein (P8) heterogeneity of rice dwarf virus (RDV) exists not only in purified virus particles, but also in RDV-infected rice, transgenic rice expressing P8, E. coli expression of P8 product and the in vitro translation products of S8. N-terminal amino acid seq uencing revealed that P8 is a cleavage product of P8'. The cleavage oc curs specifically at the residues of Asp(362) and pro(363). The functi on of the proteolytic processing is unknown.
