4 авг. 2009 г. · Catalases are ubiquitous enzymes that prevent cell oxidative damage by degrading hydrogen peroxide to water and oxygen (2H2O2 → 2 H2O + O2) ...
Molecular mechanism While the complete mechanism of catalase is not currently known, the reaction is believed to occur in two stages: H2O2 + Fe(III)-E → H2O + ...
Catalase (CAT) is an ubiquitous tetrameric heme-containing enzyme that catalyzes the dismutation of two molecules of H2O2 into water and oxygen.
The enzyme catalase converts solar radiation into reactive oxidant species (ROS). In this study, we report that several bacterial catalases ...

Catalase is a heme containing enzyme which catalyses the breakdown of hydrogen peroxide to water and molecular oxygen. It also has a peroxidase activity ...
The catalytic mechanism of catalases is a two-step process in which catalase heme Fe3+ reduces one hydrogen peroxide molecule to water and generates a porphyrin ...
Catalases break down hydrogen perox- ide by a two-stage mechanism in which hydrogen peroxide alternately oxidises and reduces the haem iron at the active site.
It is a significant component of the cell defense mechanism against oxidative stress, as it scavenges hydrogen peroxide (H2O2) to oxygen and water (Foyer and ...
