---|---|---|---|
HPV-1 L1 | BPV-1 L1 | SV40 VP1 | |
CRPV L1 | 58 (75) | 48 (67) | 19 (42) |
HPV-1 L1 | 48 (69) | 16 (37) | |
BPV-1 L1 | 17 (39) |
L2 | L2 | VP2/VP3 | |

The percentage of identical (left) and similar (in parentheses) residues is given for several L1–L1, L1–VP1, L2–L2, and L2–VP2/VP3 comparisons. Correlation of L1 sequences to random sequences the same length as VP1 gave an identity of 14 to 16% and a similarity of 40 to 42%.
