19F NMR study of the interactions of fluoride with superoxide dismutase and hemoglobin in erythrocytes.
F- added to an erythrocyte suspension shows two separated resonances arisen from intra and extracellular compartments. Cu, Zn superoxide dismutase dominates the longitudinal relaxation rate of the intracellular F- resonance, while diamagnetic interactions with hemoglobin contribute mainly to the transversal relaxation rate.
