Metallobiochemistry of RNA. Co(NH3)6(3+) as a probe for Mg2+(aq) binding sites

Abstract

Co(NH3)6(3+) may serve as a probe of outer sphere complexation by Mg(H2O)6(2+) with RNA. The number of metal binding sites may be quantitatively assessed by optical spectroscopy (55-130, depending on background [K+]). Novel coordination-induced features have been observed in circular dichroism spectra.
