WebIron is indispensable for DNA synthesis and a host of metabolic processes (Cazzola et al., 1990). Iron starvation arrests proliferation, presumably because the metal is required by ribonucleotide reductase and other enzymes involved in cell division (Hoffbrand et al., 1976). WebThe interaction of [Fe(2)L(3)](4+) metallosupramolecular helicates (L = C(25)H(20)N(4)) with DNA duplexes containing bulges has been studied by measurement of the DNA melting temperature and gel electrophoresis. This study was aimed at exploring binding affinities of the helicates for DNA bulges of various sizes and nucleotide sequences.
