Blotched snakehead virus is a new aquatic birnavirus that is slightly more related to avibirnavirus than to aquabirnavirus. (1/1)

By different approaches, we characterized the birnavirus blotched snakehead virus (BSNV). The sequence of genomic segment A revealed the presence of two open reading frames (ORFs): a large ORF with a 3,207-bp-long nucleotide sequence and a 417-nucleotide-long small ORF located within the N-terminal half of the large ORF, but in a different reading frame. The large ORF was found to encode a polyprotein cotranslationally processed by the viral protease VP4 to generate pVP2 (the VP2 precursor), a 71-amino-acid-long peptide ([X]), VP4, and VP3. The two cleavage sites at the [X]-VP4 and VP4-VP3 junctions were identified by N-terminal sequencing. We showed that the processing of pVP2 generated VP2 and several small peptides (amino acids [aa] 418 to 460, 461 to 467, 468 to 474, and 475 to 486). Two of these peptides (aa 418 to 460 and 475 to 486) were positively identified in the viral particles with 10 additional peptides derived from further processing of the peptide aa 418 to 460. The results suggest that VP4 cleaves multiple Pro-X-Ala downward arrow Ala motifs, with the notable exception of the VP4-VP3 junction. Replacement of the members of the predicted VP4 catalytic dyad (Ser-692 and Lys-729) confirmed their indispensability in the polyprotein processing. The genomic segment B sequence revealed a single large ORF encoding a putative polymerase, VP1. Our results demonstrate that BSNV should be considered a new aquatic birnavirus species, slightly more related to IBDV than to IPNV.  (+info)

Avibirnavirus is a genus of viruses in the family *Birnaviridae*, which infect birds. This genus contains two species: Avian necrotic enteritis virus and Infectious bursal disease virus. These viruses are non-enveloped, with icosahedral symmetry and a diameter of about 60 nm. The genome is composed of double-stranded RNA divided into two segments, labeled A and B. Segment A (approximately 3 kb) encodes for the viral polyprotein, while segment B (approximately 2.8 kb) encodes for the viral RNA-dependent RNA polymerase. Avibirnavirus infections can cause significant economic losses in the poultry industry due to diseases such as necrotic enteritis and Gumboro disease.
