title: The 42K protein of rice dwarf virus is a post-translational cleavage product of the 46K outer capsid protein.
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 sequencing revealed that P8 is a cleavage product of P8'. The cleavage occurs specifically at the residues of Asp362 and Pro363. The function of the proteolytic processing is unknown.
