Fitted kinetic data for the reduction of an Fe(III) complex with NTA at different [Fe(III)]/[OmcA] ratios at pH 7.0, including 3:1 (plot a), 6:1 (plot b), and 12:1 (plot c). The initial solution conditions were as follows: for plot a, 1.5 × 10−4 M Fe(III), 2.25 × 10−4 M NTA, and 5.0 × 10−5 M OmcA; for plot b, 2 × 10−4 M Fe(III), 3 × 10−4 M NTA, and 3.3 × 10−5 M OmcA; and for plot c, 2.4 × 10−4 M Fe(III), 3.6 × 10−4 M NTA, and 2 × 10−5 M OmcA.
