Table 6. Frequency of conserved motifs in novel HPV types.

Various conserved motifs in HPV LCR, E6 and E7 regions are identified. The codes for degenerate nucleotides are as follows: K=G or T; W= A or T; M=A or C; R=G or A; Y=T or C; B=G, T, C; D=G, A, T. N represents any nucleotide, and X represents any amino acid.
