Characterization 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 کاملIn vitro transactivation of baculovirus early genes by nuclear extracts from Autographa californica nuclear polyhedrosis virus-infected Spodoptera frugiperda cells.
Nuclear extracts, prepared from Autographa californica nuclear polyhedrosis virus-infected Spodoptera frugiperda cells during a time course of infection, were analyzed for activation of early gene transcription and for late gene transcription. The templates used in the in vitro transcription assays contained promoters for baculovirus genes that have been classified as immediate early, delayed e...
متن کاملAutographa californica nuclear polyhedrosis virus DNA polymerase: measurements of processivity and strand displacement.
The DNA polymerase (DNApol) of Autographa californica nuclear polyhedrosis virus was purified to homogeneity from recombinant baculovirus-infected cells. DNApol was active in polymerase assays on singly primed M13 template, and full-length replicative form II product was synthesized at equimolar ratios of enzyme to template. The purified recombinant DNApol was shown to be processive by template...
متن کاملEffects of Temperature and pH on Survival of Free Nuclear Polyhedrosis Virus of Autographa californica.
The effects of temperature and low pH on replication and survival of nonoccluded Autographa californica nuclear polyhedrosis virus were investigated. No virus replication or formation of polynuclear inclusion bodies occurred at 37 degrees C. The virus was immediately inactivated upon exposure to pH 2.0 and was inactivated within 1 h at pH 4.0. The virus titer slowly declined, a 3-orders of magn...
متن کاملA mechanism for negative gene regulation in Autographa californica multinucleocapsid nuclear polyhedrosis virus.
The Autographa californica multinucleocapsid nuclear polyhedrosis virus (AcMNPV) ie-1 gene product (IE-1) is thought to play a central role in stimulating early viral transcription. IE-1 has been demonstrated to activate several early viral gene promoters and to negatively regulate the promoters of two other AcMNPV regulatory genes, ie-0 and ie-2. Our results indicate that IE-1 negatively regul...
