DNA sequence and genome organization of genital human papillomavirus type 6b.

The complete nucleotide sequence of the circular double-stranded DNA of the genital human papillomavirus type 6b (HPV6b) comprising 7902 bp was determined and compared with the DNA sequences of human papillomavirus type 1a (HPV1a) and bovine papillomavirus type 1 (BPV1). All major open reading frames are located on one DNA strand only. Their arrangement reveals that the genomic organization of HPV6b is similar to that of HPV1a and BPV1.
