Isolation, characterization, and comparison of recombinant DNAs derived from genomes of human hepatitis B virus and woodchuck hepatitis virus

Abstract

The human hepatitis B virus (HBV) and the woodchuck hepatitis virus (WHV) are closely related by several criteria and belong to the same class of DNA viruses. The DNA genomes from these viruses are difficult to obtain in quantities required for biochemical analysis. We have, therefore, cloned these two DNAs in the vector lambda gtWES and subcloned into the kanamycin resistance plasmid pA01. Comparison of the recombinant DNAs with authentic viral DNAs by specific hybridization, size, and restriction enzyme analysis suggests that the recombinants contain the complete genome of each virus. The nominal size of the cloned HBV genome was 3150 base pairs, compared to 3200 base pairs for the cloned WHV genome. The small amount of nucleic acid homology previously reported between the HBV and WHV DNAs could be demonstrated between the cloned viral DNAs.
