Catalase - an overview | ScienceDirect Topics
Catalase (EC 1.11.1.6) is a tetrameric 240-kDa enzyme with ferriprotoporphyrin at its active site that is present in the peroxisome of most organisms containing cytochrome machinery (Hillar, 1993; Deisseroth and Dounce, 1970).
Understanding Catalase: Function, Role, and Structure - SuchScience
2024年4月14日 · Catalase is an important antioxidant enzyme that helps defend cells against oxidative stress. It breaks down hydrogen peroxide, a reactive oxygen species that can damage cellular components. The enzyme rapidly converts hydrogen peroxide into water and oxygen.
Therapeutic potentials of catalase: Mechanisms, applications, and ...
Catalase, an enzyme ubiquitous in living organisms, plays a pivotal role in mitigating oxidative stress by catalyzing the decomposition of hydrogen peroxide (H 2 O 2) into water and oxygen. Mechanistically, this action prevents the accumulation of reactive oxygen species (ROS) and consequent oxidative damage to cells and tissues.
