The electrostatic potential of B-DNA.
Electrostatic potentials around DNA are obtained by solving the nonlinear Poisson-Boltzmann (PB) equation. The detailed charge distribution of the DNA and the different polarizabilities of the macromolecule and solvent are included explicitly in the calculations. The PB equation is solved using extensions of a finite difference approach applied previously to proteins. Electrical potentials and ...
متن کاملThe molecular electrostatic potential, steric accessibility and hydration of Dickerson's B-DNA dodecamer d(CpGpCpGpApApTpTpCpGpCpG).
The paper presents the results of computation of the electrostatic potential and steric accessibility of the B-DNA self-complementary dodecamer CGCGAATTCGCG following the geometry of the recent single crystal structure of Dickerson et al. This structure shows significant variations from classical B-DNA; their influences on the calculated properties are discussed. The results are related to gene...
متن کاملDeppdb - DNA electrostatic Potential Properties Database: electrostatic Properties of genome DNA Elements
The electrostatic properties of genome DNA influence its interactions with different proteins, in particular, the regulation of transcription by RNA-polymerases. DEPPDB--DNA Electrostatic Potential Properties Database--was developed to hold and provide all available information on the electrostatic properties of genome DNA combined with its sequence and annotation of biological and structural p...
متن کاملThe molecular electrostatic potential and steric accessibility of A-DNA.
The molecular electrostatic potential and steric accessibility of A-DNA are computed for base sequences (dG.dC)n and (dA.dT)n. An interpretation of the results in terms of the structure of A-DNA is provided and differences with respect to other forms of DNA, namely B-DNA and Z-DNA, are discussed.
متن کاملThe molecular electrostatic potential and steric accessibility of poly (dA-dT). poly (dA-dT) in various conformations: B-DNA, D-DNA and 'alternating-B' DNA.
The influence of conformational changes on the molecular electrostatic potential and the steric accessibility of the double stranded polynucleotide poly (dA-dT). poly (dA-dT) are investigated by calculating these properties for three different conformations : B-DNA, D-DNA and alternating-B DNA.
