Members of the SV40-polyoma subgroup of papovaviruses share homologous sequences which have been conserved during evolution. The genome of HD virus displays homologies both to the origin of SV40 DNA replication and to the region coding for the VPI capsid protein. As in the case of SV40, both regions are discontinuously arranged in the HD genome.
乳头多瘤空泡病毒科的SV40-多瘤病毒亚组成员具有同源序列,这些序列在进化过程中得以保留。丁型肝炎病毒的基因组与SV40 DNA复制起点以及编码VP1衣壳蛋白的区域均显示出同源性。与SV40的情况一样,这两个区域在丁型肝炎病毒基因组中都是不连续排列的。
