DNA and ATP binding activities of the baculovirus DNA helicase P143.
نویسندگان
چکیده
P143 is a DNA helicase that tightly binds both double-stranded and single-stranded DNA. DNA-protein complexes rapidly dissociated in the presence of ATP and Mg(2+). This finding suggests that ATP hydrolysis causes a conformational change in P143 which decreases affinity for DNA. This supports the model of an inchworm mechanism of DNA unwinding.

Characterization of the interaction between the baculovirus ssDNA-binding protein (LEF-3) and putative helicase (P143).
LEF-3 and P143 are two of six proteins encoded by the Autographa californica multinucleocapsid nucleopolyhedrovirus genome which are required for DNA replication in transient replication assays. LEF-3 has the properties of an ssDNA-binding protein and P143 exhibits amino acid sequence homology to helicases. In this report, the interaction of LEF-3 and P143 was studied by yeast two-hybrid and im...
متن کاملThe Trichoplusia ni granulovirus helicase is unable to support replication of Autographa californica multicapsid nucleopolyhedrovirus in cells and larvae of T. ni.
Baculovirus DNA helicases are essential for replication and are determinants of host range. Helicases of Autographa californica multicapsid nucleopolyhedrovirus (AcMNPV) and Trichoplusia ni granulovirus (TnGV) differ markedly, although both viruses replicate efficiently in the cabbage looper, T. ni. To determine whether the TnGV helicase (P137) could support replication of AcMNPV in T. ni cells...
متن کاملDrosophila melanogaster RECQ5/QE DNA helicase: stimulation by GTP binding.
The Drosophila melanogaster RECQ5/QE gene encodes a member of the DNA helicase family comprising the Escherichia coli RecQ protein and products of the human Bloom's, Werner's, and Rothmund-Thomson syndrome genes. The full-length product of RECQ5/QE was expressed in the baculovirus system and was purified. Gel filtration experiments indicated that RECQ5/QE was present in an oligomeric state. The...
متن کاملCharacterization of the enzymatic activity of hChlR1, a novel human DNA helicase.
Recently, we cloned two highly related human genes, hChlR1 ( DDX11 ) and hChlR2 ( DDX12 ), which appear to be homologs of the Saccharomyces cerevisiae CHL1 gene. Nucleotide sequence analysis suggests that these genes encode new members of the DEAH family of DNA helicases. While the enzymatic activity of CHL1 has not been characterized, the protein is required for the maintenance of high fidelit...
متن کاملThe nuclease activity of the yeast DNA2 protein, which is related to the RecB-like nucleases, is essential in vivo.
Saccharomyces cerevisiae Dna2 protein is required for DNA replication and repair and is associated with multiple biochemical activities: DNA-dependent ATPase, DNA helicase, and DNA nuclease. To investigate which of these activities is important for the cellular functions of Dna2, we have identified separation of function mutations that selectively inactivate the helicase or nuclease. We describ...
