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

Abstract

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. The putative early region includes two large open reading frames E1 and E2 with marked amino acid sequence homologies to HPV1a and BPV1 which are flanked by several smaller frames. The internal part of E2 completely overlaps with another open reading frame E4. The putative late region contains two large open reading frames L1 and L2. The L1 amino acid sequences are highly conserved among analyzed papillomavirus types. By sequence comparison, potential promoter, splicing and polyadenylation signals can be localized in HPV6b DNA suggesting possible mechanisms of genital papillomavirus gene expression.
