Complete in vitro replication of SV40 DNA and chromatin in saponin-treated permeable cells.
نویسندگان
چکیده
A permeable cell system has been developed by treatment with saponin for studying in vitro replication of DNA and chromatin. DNA replication of simian virus 40 nucleoprotein complexes (SV40 chromatin) in saponin-treated permeable cells was found to be more efficient than that in digitonin-treated permeable cells. Autoradiography of the agarose-gel revealed that [alpha-32P]dCTP was incorporated into SV40 DNA I, II and replicating intermediates. The time course of the incorporation indicated complete replication of SV40 DNA and chromatin with a full number of nucleosomes. The saponin-treated permeable cell system will serve as a useful system for studying in vitro replication of DNA and chromatin in eukaryotic cells.

Complete in vitro DNA replication of SV40 chromatin in digitonin-treated permeable cells.
A permeable cell system has been developed by treatment with digitonin for studying in vitro DNA replication of chromatin. DNA replication of simian virus 40 nucleoprotein complexes (SV40 chromatin) in digitonin-treated permeable cells was analyzed by electrophoresis in agarose-gel. Autoradiography of the agarose-gel revealed that [32P]dCTP was incorporated in SV40 DNA I, II and replicating int...
متن کاملEffects of cell cycle dependent histone H1 phosphorylation on chromatin structure and chromatin replication.
We have reconstituted salt-treated SV40 minichromosomes with differentially phosphorylated forms of histone H1 extracted from either G0-, S- or M-phase cells. Sedimentation studies revealed a clear difference between minichromosomes reconstituted with S-phase histone H1 compared with histone H1 from G0- or M-phase cells, indicating that the phosphorylation state of histone H1 has a direct effec...
متن کاملReplication of SV40 chromatin in extracts from eggs of Xenopus laevis.
Simian virus 40 (SV40) nucleoprotein complexes were prepared from lytically infected cells and used as primer-templates for DNA replication in protein extracts from Xenopus eggs. We found that nucleoprotein containing replicating SV40 DNA served as primer-template while nucleoprotein with nonreplicating SV40 DNA was ineffective. In vitro DNA synthesis begins with short DNA fragments ("Okazaki f...
متن کاملAccessibility to topoisomerases I and II regulates the replication efficiency of simian virus 40 minichromosomes.
We determined the effects of chromatin structure on template accessibility to replication factors and used three different templates as substrates for simian virus 40 (SV40) DNA replication in vitro: native and salt-treated SV40 minichromosomes and protein-free SV40 DNA. Native minichromosomes contain histone H1 and numerous nonhistone proteins in addition to the core histones, whereas salt-tre...
متن کاملEffects of VM26, a specific inhibitor of type II DNA topoisomerase, on SV40 chromatin replication in vitro.
We have examined the influence of VM26 (teniposide), a specific inhibitor of mammalian type II DNA topoisomerase, on the replication of SV40 minichromosomes in vitro. The replication system we used consists of replicative intermediate SV40 chromatin as substrate which is converted to mature SV40 chromatin in the presence of ATP, deoxynucleotides and a protein extract from uninfected cells. The ...
