pubmed:abstractText |
We have examined the kinetics of the interaction between endodeoxyribonuclease EcoRI (EC 3.1.23.13) and nine linear DNA fragments that range in size between 34 and 6,200 base pairs and contain the EcoRI site of plasmid pBR322 in a central location. The kinetic parameters governing both formation and decay of specific endonuclease . DNA complexes increase 8-fold with increasing chain length over this size range. In contrast, equilibrium competition experiments demonstrated that the intrinsic affinity of endonuclease for its recognition sequence is independent of DNA chain length over this range. Thus, DNA sequences outside the recognition site enhance the rate at which EcoRI endonuclease locates or leaves its recognition site without affecting the intrinsic thermodynamic parameters of site-specific interaction. These results are consistent with a facilitated diffusion mechanism for specific DNA site location by this enzyme.
