Circular dichroism (CD) spectra of d(CCCCGGGG) in the presence of Co(NH3)6(3+) are very similar to spectra of r(CCCCGGGG). In contrast, B-form characteristics are observed for d(CCCCGGGG) in the presence of Na+ and Mg2+, even at high salt concentrations. Spermidine induces modest changes of the CD of d(CCCCGGGG). The NMR chemical shifts of the nonexchangeable protons of d(CCCCGGGG) in the absence and presence of Co(NH3)6(3+) were assigned by proton two-dimensional (2D) NOESY and COSY… CONTINUE READING
