Mithramycin (MTR) is an antitumor compound that inhibits RNA and DNA polymerase action by forming a non covalent complex with double strand DNA, in the presence of divalent cations. We have shown that in the presence of Mg2+, MTR binds to right-handed poly(dG-m5dC) as a dimer in the right-handed screwness conformation but cannot bind to left-handed poly(dG-m5dC).
