Biological role of restriction enzymes
WebThis methylation produces a bulky hydrophobic patch on the floor of the major groove of B-DNA which plays an important role in the mechanism of inhibition of EcoRI restriction activity. However, with the exception of small perturbations in the immediate vicinity of the methyl groups, the structure is virtually unchanged.
