DNA Packaging In Bacteriophage: Is Twist Important?
If the DNA within the bacteriophage is assumed to be un-deformed B-DNA (Holzwarth et al., 1974a,b); these features are better captured when the internalized DNA is assumed to have both anisotropic packaging and distorted structure. The similarities between the circular dichroism spectra of the ... Access Doc

The FX174 Protein J Mediates DNA Packaging And Viral ...
Containing the smaller DNA-binding protein cannot be generated due to procapsid instability during DNA packaging. However, chimeric a3 and G4 phages, containing the fX174 DNA-binding protein in place of the endogenous J protein, assemble and are infectious, but are less dense than the respective wild-type species. In addition, host cell attachment ... Fetch Full Source

Structure And Inhibition Of Herpesvirus DNA Packaging ...
Addition of UL89 is the DNA cut into smaller fragments. This observation indicates that these proteins mediate a concerted reaction of DNA recognition and cleavage (5). Proteins homologous to UL89 are known in all herpesviruses, as are the other terminase subunits, thus indicating that the DNA packaging mechanism is highly conserved (9). The ... Read Content

Mechanics Of DNA Packaging In Viruses - PNAS
The problem of DNA packing is intriguing not only on the grounds of sheer geometric crowding, but also because of the recognition that the regions within which DNA is packaged (such as in a viral capsid) have linear dimensions that are comparable to the persistence length of the DNA, resulting in a ...

Epigenomics - Wikipedia
Nucleosomes and the DNA connecting form a 10 nm diameter chromatin fiber, which can be further condensed. Chromatin packaging of DNA varies depending on the cell cycle stage and by local DNA region. The degree to which chromatin is condensed is associated with a certain transcriptional state. ... Read Article
