Determination of fast proton exchange rates of biomolecules by NMR using water selective diffusion experiments.

abstract：:Azotobacter vinelandii (Av) and chroococcum (Ac) ferredoxin I contain [3Fe-4S]1 + 0 and [4Fe-4S]2+1+ clusters, when isolated aerobically, which undergo one-electron redox cycles at potentials of -460 +/- 10 mV (vs SHE) at pH 8.3 and -645 +/- 10 mV, respectively. The X-ray structure of Fd I (Av) reveals that the N-term...
