Complete genome and phylogenetic position of bovine papillomavirus type 7.
Six bovine papillomavirus (BPV) types and 16 putative BPV types have been reported previously. Here, the complete genome sequence of BAPV6, a novel putative BPV type isolated from cattle in Japan, was determined by using multiple-primed rolling-circle amplification. The genome consisted of 7412 bp (G+C content of 46 mol%) that encoded five early (E1, E2, E4, E6 and E7) and two late (L1 and L2) genes, but did not encode the E5 gene. The E6 protein contained a non-consensus CxxC(x)(33)CxxC and a consensus CxxC(x)(29)CxxC zinc-binding domain, and the E7 protein lacked the LxCxE motif. The nucleotide sequence of the L1 open reading frame (ORF) was related most closely (57-58 %) to the L1 ORF of member(s) of the genera Betapapillomavirus, Gammapapillomavirus and Pipapillomavirus. Phylogenetic analysis based on the complete L1 ORF suggests that BAPV6 should be classified in a novel genus in the family Papillomaviridae as BPV-7.
