Each of the elementary reaction steps in both the activation process and catalytic cycle of the cytochrome c peroxidase of Pseudomonas aeruginosa was characterized using stopped-flow methods. A synthesis of these data led to the establishment of a quantitative model for the action of this enzyme. Comparisons were made between experimental data and calculations over a wide range of enzyme, reductant and H2O2 concentrations. Close agreement was found between empirical and simulated reaction time courses from millisecond to tens of seconds time ranges, giving us confidence in the validity of the quantitative model of this enzyme's actions.

Kinetics Of

A procedure is described for the purification of cytochrome c peroxidase from Pseudomonas aeruginosa involving extraction by sonication, followed by acid precipitation and chromatography on only two types of gel. The final preparation had a purity ratio A407/A280 of 4.2, and was found to be essentially pure by isoelectric focusing. The enzyme was shown to be unstable during degassing under vacuum except in the presence of detergent. The kinetics of CO binding to dithionite-reduced peroxidase were studied with stopped-flow and flash-photolysis techniques, and the results obtained between pH 5 and 7 suggest the existence of two forms of dithionite-reduced enzyme in slow equilibrium.
