Transient-state kinetics of ERS regeneration from wt-ElDyP cmpd I. (A) Spectral transition of 2.5 μM wt cmpd I reduced by 2.5 μM ABTS at pH 3.5 in the presence of 10 μM ascorbate. The cmpd I was produced by reacting 2.5 μM wt-ElDyP with 2.5 μM H2O2 followed by 2-s delay. (B) Regeneration of ERS from cmpd I monitored at 406 nm. The inset represents determination of second-order rate constant kERS in the presence of ABTS. (C) pH-dependence of 2.5 μM wt cmpd I reacted with 0.5 μM ABTS at various pH.
