Occupancy of the two calcium-binding sites of codfish parvalbumin by the redox-active probe ions Yb 3 + and Eu 3 + causes the average tryptophan (Trp) fluorescence lifetime in this protein to decrease and become non-exponential from the single exponential values found for Ca 2 + and La 3 + of 4.45 n
