Molecular polarity in DNA-protein recognition--the case of lambda-repressor-operator system.
The charge distribution of lambda-repressor suggests that the molecular electrostatic polarity may accelerate the non-specific binding of the protein to the DNA molecule. The repressor molecule has a patch of positive charge within the first 26 residues which may contribute a non-specific binding surface. In addition, electrostatics may play an important role and account for why proteins form and use dimers in many specific DNA-protein recognition processes.
