Stopped-flow kinetic study of the peroxidase reactions of mangano-microperoxidase-8.

We have investigated the kinetics for the peroxidase-type reaction of mangano microperoxidase 8 (Mn(III)-MP8) by the time-resolved and single-wavelength stopped-flow technique. The formation of intermediate and its subsequent reaction with substrates were studied separately. Oxidation of Mn(III)-MP8 by H2O2 at pH 10.
