Electrostatic deformation of DNA by a DNA-binding protein.
Complementary electrostatic interactions between negatively charged B-DNA and a positively charged array on the lambda Cro repressor protein are shown to substantially contribute to the formation energy of sequence-specific and nonspecific Cro-DNA complexes. The electrostatic interactions favor Cro binding to a bent form of DNA, a geometry which optimizes hydrogen-bonding contacts between Cro a...
متن کاملComparative Investigation of R213G Mutation in DNA-Binding Domain of P53 Protein via Molecular Dynamics Simulation
Introduction: P53 is a tumor suppressor protein with numerous missense mutations identified in its gene. These mutations are observed in a vast number of cancers. R213G is one of them which has a role in metastatic lung cancers. In this research, R213G was studied in comparison with the wild type via molecular dynamics simulation. Method: For the three-dimensional structure of the wild-type P53...

متن کاملModeling spatial correlation of DNA deformation: DNA allostery in protein binding.
We report a study of DNA deformations using a coarse-grained mechanical model and quantitatively interpret the allosteric effects in protein-DNA binding affinity. A recent single-molecule study (Kim et al. Science 2013, 339, 816) showed that when a DNA molecule is deformed by specific binding of a protein, the binding affinity of a second protein separated from the first protein is altered. Exp...
