in addition to an analysis of the mechanism of porphyrin-mediated strand breakage in terms of the dna cleavage mechanism of methidium-propyl-iron-edta and fe-bleomycin , the potential of the cationic metalloporphyrins as footprinting probes and as new `` '' reporter ligands '' '' for dna is presented and discussed .
