An enhancer of DNA replication.
cmp, a nucleotide sequence element in the plasmid pT181 of Staphylococcus aureus, acts as an enhancer of DNA replication. When cmp is present on an unrelated vector along with the pT181 origin of replication, it increases the ability of the linked pT181 origin to compete with a coresident pT181 plasmid for the initiator protein RepC. cmp is contained within a 156-base-pair segment, and its dele...
متن کاملAn enhancer of recombination in polyomavirus DNA.
Previous work from this laboratory has indicated that intramolecular homologous recombination of polyomavirus (Py) DNA is dependent upon promoter structure or function. In this report, we demonstrate that Py DNA contains not two but three binding sites for transcription factor YY1, all located on the late side of viral origin of replication (ori) and the third well within the VP1 coding sequenc...
متن کاملAn expanded view of bacterial DNA replication.
A protein-interaction network centered on the replication machinery of Bacillus subtilis was generated by genome-wide two-hybrid screens and systematic specificity assays. The network consists of 91 specific interactions linking 69 proteins. Over one fourth of the interactions take place between homologues of proteins known to interact in other organisms, indicating the high biological signific...
متن کاملInitiation of DNA replication at the human β-globin 3′ enhancer
The origin of DNA replication in the human beta-globin gene contains an initiation region (IR) and two flanking auxiliary elements. Two replicator modules are located within the upstream auxiliary sequence and the IR core, but the functional sequences in the downstream auxiliary element are unknown. Here, we use a combination of benzoylated-naphthoylated DEAE (BND) cellulose purification and na...
متن کاملDNA REPLICATION AND SYNTHESIS OF DNABINDING PROTEINS IN THE CHLOROPLASTS OF A CALLUS CULTURE
Continuous labelling of callus with H-thymidine results in intermittent peaks of H-DNA per chloroplast, showing synchrony of division. The increase in H-DNA could be due to several replication rounds, and the drop to successive plastid divisions without intervening DNA synthesis. The level of DNA-binding proteins in the chloroplast parallels the peaks of plastidal DNA synthesis; such pro...
