The excited energy of ethidium transferred to meso-tetrakis(N-methylpyridinium-4-yl) porphyrin (TMPyP) when they are simultaneously intercalated between DNA base-pairs. The minimum number of base-pairs between ethidium and TMPyP required for excited ethidium to emit a photonwas 36A or 10.6 base-pairs. The distance was extended to 72 A or 21.2 base-pairs in the presence of 100mM Mg2+ ions although the conformation of TMPyP complexed with DNA, whichwas investigated by circular and linear dichroism spectroscopy, was unaffected by the presence of Mg2+ ions.
