Complete nucleotide and amino acid sequences and genetic organization of porcine kobuvirus, a member of a new species in the genus Kobuvirus , family Picornaviridae

Complete nucleotide and amino acid sequences and genetic organization of porcine kobuvirus, a... Kobuvirus is a new genus in the family Picornaviridae . Two species are currently known: Aichi virus (human kobuvirus) and Bovine kobuvirus (U-1). In this study, the complete nucleotide and amino acid sequences and genetic organization of porcine kobuvirus (Kobuvirus/swine/S-1-HUN/2007/Hungary, EU787450) were determined. The structure of the S-1-HUN genome, VPg–5′UTR–leader protein–structural proteins (VP0, VP3, VP1)–non-structural proteins (2A–2C, 3A–3D)–3′UTR–poly(A) tail, was found to be typical of picornavirus. The 8210-nucleotide (nt)-long RNA genome contains a large open reading frame (7467 nt) encoding a potential polyprotein precursor of 2488 amino acids (aa) that has 57/56% and 63/64% nt/aa identity with Aichi virus and U-1, respectively. The 5′UTR contains a hepacivirus/pestivirus-like internal ribosomal entry site (IRES type IV group-B-like) with conserved pseudoknot, II and IIIa–f domains. A tandem repeat (a 30-amino-acid-long motif) was detected in 2B. Thirty-nine (65%) of the 60 fecal samples from pigs under the age of 6 months at the tested farm were positive (the incidence was 90% under the age of 3 weeks). Porcine kobuvirus belongs to a potential new species—the third—in the genus Kobuvirus. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals
