Hexagonally packed DNA within bacteriophage T7 stabilized by curvature stress.
نویسنده
چکیده
A continuum computation is proposed for the bending stress stabilizing DNA that is hexagonally packed within bacteriophage T7. Because the inner radius of the DNA spool is rather small, the stress of the curved DNA genome is strong enough to balance its electrostatic self-repulsion so as to form a stable hexagonal phase. The theory is in accord with the microscopically determined structure of bacteriophage T7 filled with DNA within the experimental margin of error.

Nonuniform Donnan Equilibrium within Bacteriophages Packed with Dna
The curvature stress of DNA packed inside a phage is balanced against its electrostatic self-interaction. The DNA density is supposed nonuniform and as a result the Donnan effect is also inhomogeneous. The coarse-grained DNA density is a nonlinear function of the DNA radius of curvature at a given position inside the bacteriophage. It turns out that a region (or regions) exists totally free fro...
متن کاملGenetic analysis of the interaction between bacteriophage T7 DNA polymerase and Escherichia coli thioredoxin.
Gene 5 protein of bacteriophage T7 is a nonprocessive DNA polymerase. During infection of Escherichia coli, T7 annexes the host protein thioredoxin for use as a processivity factor for T7 DNA polymerase. We describe here a genetic method to investigate the interaction between T7 gene 5 protein and E. coli thioredoxin. The strategy is to use thioredoxin mutants that are unable to support the gro...
متن کاملHybrid Methods Reveal Multiple Flexibly Linked DNA Polymerases within the Bacteriophage T7 Replisome.
The physical organization of DNA enzymes at a replication fork enables efficient copying of two antiparallel DNA strands, yet dynamic protein interactions within the replication complex complicate replisome structural studies. We employed a combination of crystallographic, native mass spectrometry and small-angle X-ray scattering experiments to capture alternative structures of a model replicat...
متن کاملMolecular interactions in the priming complex of bacteriophage T7.
The lagging-strand DNA polymerase requires an oligoribonucleotide, synthesized by DNA primase, to initiate the synthesis of an Okazaki fragment. In the replication system of bacteriophage T7 both DNA primase and DNA helicase activities are contained within a single protein, the bifunctional gene 4 protein (gp4). Intermolecular interactions between gp4 and T7 DNA polymerase are crucial for the s...
متن کاملChoreography of bacteriophage T7 DNA replication.
The replication system of phage T7 provides a model for DNA replication. Biochemical, structural, and single-molecule analyses together provide insight into replisome mechanics. A complex of polymerase, a processivity factor, and helicase mediates leading strand synthesis. Establishment of the complex requires an interaction of the C-terminal tail of the helicase with the polymerase. During syn...
