REDOX AND SPIN-STATE CONTROL OF THE ACTIVITY OF A DIHEME CYTOCHROME C PEROXIDASE - Spectroscopic studies

摘要

Hydrogen peroxide formed in cells, as the result of incomplete reduction of oxygen, can be removed essentially by two ways: by peroxidases in a process of reduction to water or by catalase in a dismutation reaction. The actions of these enzymes are essential to prevent the accumulation of hydrogen peroxide, diminishing the risk of peroxide-induced damage of cell constituents [1].
