... resonances without the concomitant appearance of other signals in other parts of the spectrum. This result could be a consequence of the paramagnetic properties of Fe(II), or it might arise from the presence of ... Fe 3+ Addition of Fe 2+ induced the displacement of several resonances in the [ 1 H, 15 N]-HSQC NMR spectrum of CyaY, but the most striking consequenc...
