conditions under which phospho-rii x camp relaxes superhelical phi x174 dna lead to transient formation of a dna-phospho-rii x camp complex via dna strand breakage and covalent attachment of the dna to a tyrosine residue of phospho-rii x camp via a phospho-rii x camp depends on the presence of camp and is altered by changes in the degree of phosphorylation of rii .
