2. Artificial cleavage site recognized by plum pox potyvirus protease in Escherichia coli.
A synthetic plum pox virus (PPV) NIb-CP cleavage site was recognized by a PPV protease in an in vivo Escherichia coli expression system. The presence of the natural NIb-CP cleavage site did not affect processing at the artificial one. However, although both the proteases and the cleavage sites of PPV and tobacco etch virus show high sequence homology, a simi

6. Novel catalytic activity associated with positive-strand RNA virus infection: nucleic acid-stimulated ATPase activity of the plum pox potyvirus helicaselike protein.
The cylindrical inclusion protein of potyviruses contains the so-called nucleoside triphosphate binding motif, an amino acid sequence motif present in proteins encoded by most positive-strand RNA viruses, some double-strand RNA viruses, apparently all groups of double-strand DNA viruses, and also several single-strand DNA viruses. Further sequence analysis h

7. The motif V of plum pox potyvirus CI RNA helicase is involved in NTP hydrolysis and is essential for virus RNA replication.
The plum pox potyvirus (PPV) protein CI is an RNA helicase whose function in the viral life cycle is still unknown. The CI protein contains seven conserved sequence motifs typical of RNA helicases of the superfamily SF2. We have introduced several individual point mutations into the region coding for motif V of the PPV CI protein and expressed these proteins

8. Transgenic or Plant Expression Vector-Mediated Recombination of Plum Pox Virus
Different mutants of an infectious full-length clone (p35PPV-NAT) of Plum pox virus (PPV) were constructed: three mutants with mutations of the assembly motifs RQ and DF in the coat protein gene (CP) and two CP chimeras with exchanges in the CP core region of Zucchini yellow mosaic virus and Potato virus Y. The assembly mutants were restricted to single infe

9. RNA helicase: a novel activity associated with a protein encoded by a positive strand RNA virus.
Most positive strand RNA viruses infecting plants and animals encode proteins containing the so-called nucleotide binding motif (NTBM) (1) in their amino acid sequences (2). As suggested from the high level of sequence similarity of these viral proteins with the recently described superfamilies of helicase-like proteins (3-5), the NTBM-containing cylindrical

10. Host-Specific Involvement of the HC Protein in the Long-Distance Movement of Potyviruses
Plum pox virus (PPV) is a member of the Potyvirus genus that, in nature, infects trees of the Prunus genus. Although PPV infects systemically several species of the Nicotiana genus, such as N. clevelandii and N. benthamiana, and replicates in the inoculated leaves of N. tabacum, it is unable to infect systemically the last host. The long-distance movement de
