DNA and RNA oligonucleotides that fold to form four-stranded structures (G-quadruplexes) are known to bind heme and such complexes to catalyze 1-electron (peroxidase-like) and 2-electron (peroxygenase-like) oxidation reactions. While successful in competing with protein peroxidase enzymes in this respect, G-quadruplex•heme complexes are currently not competitive with protein enzymes with regard to the enantioselectivity of the […]
