Characterization of 3'----5' exonuclease associated with DNA polymerase of silkworm nuclear polyhedrosis virus.
3'----5' Exonuclease specific for single-stranded DNA copurified with DNA polymerase of nuclear polyhedrosis virus of silkworm Bombyx mori (BmNPV Pol). BmNPV Pol has no detectable 5'----3' exonuclease activity on single-stranded or duplex DNA. Analysis of the products of 3'----5' exonucleolytic reaction showed that deoxynucleoside monophosphates were released during the hydrolysis of single-str...
متن کاملCharacterization of DNA Polymerase Activity in Trichoplusia ni Cells Infected with Autographa californica Nuclear Polyhedrosis Virus
Nuclei isolated from Trichoplusia ni cells (TN-368) infected with Autographa californica nuclear polyhedrosis virus (AcMNPV) were used to study the replication of viral DNA. Based on DNA : DNA hybridization data, virus-specific DNA polymerase activity was insensitive to aphidicolin and novobiocin and was inhibited by ddTTP and N-ethylmaleimide. The data indicate that the AcMNPV-specific DNA pol...
متن کاملCharacterization of the nucleotide sequence of the Lymantria dispar nuclear polyhedrosis virus DNA polymerase gene region.
The DNA polymerase gene of the Lymantria dispar multinucleocapsid nuclear polyhedrosis virus (LdMNPV) was cloned and sequenced. The predicted DNA polymerase protein (1113 amino acids, 115.9K) was found to have an amino acid identity of 48% with the corresponding gene of the Autographa californica MNPV (AcMNPV). It contains five domains associated with substrate binding, primase interaction, and...
متن کاملCharacterization of a Ribonucleic Acid Polymerase Activity Associated with Purified Cytoplasmic Polyhedrosis Virus of the Silkworm Bombyx mori.
Purified cytoplasmic-polyhedrosis virus has been found to have associated with it a polymerase activity capable of catalyzing the synthesis of virus-specific, single-stranded ribonucleic acid (RNA) from the double-stranded RNA genome.
متن کاملCharacterization of nuclear polyhedrosis virus DNAs.
The nuclear polyhedrosis virus DNAs characterized and compared in this study consist of the singly-enveloped nucleocapsids (SNPV) of Trichoplusia ni and the bundles of nucleocapsids common to a single envelope (MNPV) from Spodoptera frugiperda and Rachiplusia ou. The SNPV and MNPV DNAs are very similar in hydrodynamic properties and molecular weights. In addition, the NPV DNAs are similar in si...
