abstract：:Lambda integrative recombination depends on supercoiling of the phage attachment site, attP. Using dimethylsulfate protection and indirect end-labeling, the interaction of the recombination proteins Int and IHF with supercoiled and linear attP has been studied. Supercoiling enhances the binding of Int to attP, but not...
