Synthesis of parvovirus H-1 replicative form from viral DNA by DNA polymerase gamma

Abstract The initial event in the replication cycle of parvovirus H-1 is conversion of the single-stranded linear viral DNA to the double-stranded linear replicative form. We describe here detection of an activity in uninfected cell extracts that carries out this reaction. The activity was purified and identified as DNA polymerase gamma.
