The kinetics of the enzymic oxidation of dopamine (A) by polyphenol oxidaze (E) was studied by spectrophotometrically monitoring the concentration of the reaction product, 2,3-dihydroindole-5, 6 quinone, at 470 nm. The kinetics model proposed for the reaction and the effect of pH agreed with the experimental data and the resulting rate equation is given by \documentclass{article}\pagestyle{empty}\begin{document}$$ -\frac{{d[{\rm A}]}}{{dt}} = \frac{{1.5081 \times 10^{-4} [{\rm E}_0][{\rm A]}}}{{1 + 2.0896 \times 10^6 [{\rm H}^{\rm + }]}} $$\end{document} where [A] is the concentration of dopamine (mM), [Eo] the concentration of polyphenol oxidaze (mg/1) and [H+] the concentration of hydrogen ion (M) in the reaction mixture. © John Wiley & Sons, Inc.
