We map a simplified version of the protein-DNA interaction problem into an Ising-model in a random magnetic field. The model includes a "head" which moves along the chain while interacting with the underlying spins. The head moves by using the statistical fluctuations of base openings. A Monte Carlo

โฆ Synopsis
As a model for DNA-protein interaction we have performed an STO-3G calculation on the hydrogen bonded methylguanidium* dihydrogenorthophosphate-composite system and its constituent ions. The analysis of the change in the charge distribution due to the interaction shows that the calculated -2.55 eV interaction energy is nearly purely electrostatic.
