Replication of the single-stranded DNA parvovirus H-1 involves the synthesis of a double-stranded DNA replicative form (RF). In this study, the metabolism of RF DNA was examined in parasynchronous hamster embryo cells. The initiation of RF DNA replication was found to occur late in S phase, as was the synthesis of the DNA upon which subsequent viral hemagglutinin synthesis is dependent. Evidence is presented which indicates that initiation of RF replication requires proteins synthesized in late S phase, but that concomittant protein synthesis is not required for the continuation of RF replication. The data also suggest a requirement for viral protein(s) for progeny strand synthesis. Incorporation of 5-bromo-2'-deoxyuridine (BUdR) into viral DNA resulted in an "all-or-none" inhibition of viral hemagglutinin and viral antigen synthesis. BUdR inactivation of viral protein function was used to explore the time of synthesis of viral DNA serving as template for viral RNA synthesis and the effect of viral protein on RF replication and progeny strand synthesis. Results of this study suggest that parental RF DNA is synthesized shortly after infection, and that viral mRNA is transcribed from only a few copies of the viral genome in each cell. They also support the conclusion that viral protein is inhibitory to RF DNA replication. Density labeling of RF DNA with BUdR, allowing separation of viral strand DNA (V) from viral complementary strand (C), provided additional data in support of the above findings.
