Paramagnetic Effects of Mn2+ on the Ca2+-Bound Spectra of CaM1 or CaM4.
Selected regions of [15N-1H]-HSQC spectra recorded during the Mn2+ titration of 15N-labeled CaM1 or CaM4 showing Gly-25, Gly-61, Gly-98, and Gly-134 main-chain NH peaks at different Mn2+ concentrations. For these titrations, 509 and 706 μM CaM1 and CaM4, respectively, were used.
