Autographa 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 کاملIdentification of seven putative origins of Autographa californica multiple nucleocapsid nuclear polyhedrosis virus DNA replication.
Seven putative origins of DNA replication (oris) were identified and located on the genome of Autographa californica multiple nucleocapsid nuclear polyhedrosis virus (AcMNPV), when an improved infection-dependent replication assay was used. A threefold higher yield of amplified plasmid was achieved when an m.o.i. of 1 was used (instead of 25), and another twofold increase was obtained when the ...
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 کاملAnalysis of the promoter of the Autographa californica nuclear polyhedrosis virus p10 gene.
Functional analyses of the p10 gene promoter from the Autographa californica nuclear polyhedrosis virus (AcNPV) were performed by progressively deleting the 230 nucleotides upstream from the p10 coding sequences towards the ATG codon. Truncated promoter sequences retaining the full 5' non-coding leader of p10 were inserted in front of the chloramphenicol acetyltransferase (CAT) gene, and promot...
متن کاملIdentifying the RNA polymerases that synthesize specific transcripts of the Autographa californica nuclear polyhedrosis virus.
Nuclear run-on assays carried out in the presence and absence of the RNA polymerase II inhibitor, alpha-amanitin, were used to determine the exact timing of the switch from inhibitor-sensitive transcription catalysed by host RNA polymerase II, to inhibitor-resistant transcription catalysed by the baculovirus-induced RNA polymerase. These studies revealed that the onset of alpha-amanitin-resista...
