SF-Abs derived kinetic traces of the time-dependent absorption changes at various wavelengths in the AsqJ-catalyzed epoxidation by using 2-H as the substrate. Experimental data are shown in black dots, the kinetic simulations are shown in red curves. The resulting kinetics of individual species from the simulations are shown in panel d with the following color codes: purple, the AsqJ•Fe(II)•2OG•2-H quaternary complex; red, the oxyferryl intermediate; green, the AsqJ•Fe(II)•sucinnat•product complex; gray, the AsqJ•Fe(II)•2OG ternary complex.
