Abstract |
(15)N, (13)C, and (31)P electron-nuclear relaxation times are used to determine the solution structure of the base stacked Mn(+2) -AMP complex. The nitrogen-Mn(+2) distances that are determined indicate a direct inner-sphere coordination of Mn(+2) at N(1), N(7), and the amino NH2 positions. The phosphorus-Mn(+2) distance also indicates direct coordination and this second site may explain the anomalously short Mn(+2) -C(8) distance that is found. A structure is proposed consistent with the measured distances. Comparison of Mn(+2) -carbon distances with those in the literature is made. |
