Catalase - Wikipedia
Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen. [5] It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS).
Catalase | Function & Applications | Britannica
catalase, an enzyme that brings about (catalyzes) the reaction by which hydrogen peroxide is decomposed to water and oxygen. Found extensively in organisms that live in the presence of oxygen, catalase prevents the accumulation of and protects cellular organelles and tissues from damage by peroxide , which is continuously produced by numerous ...
Catalase - an overview | ScienceDirect Topics
Catalase (EC 1.11.1.6) is one of the important antioxidant enzymes that alleviate oxidative stress to a significant amount by degradation of hydrogen peroxide into water and oxygen. It is mainly located in peroxisomes.
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.

Catalase, a remarkable enzyme: targeting the oldest ... - PubMed
2017年9月26日 — Catalase is a key enzyme in the metabolism of H2O2 and reactive nitrogen species, and its expression and localization is markedly altered in tumors. The molecular mechanisms regulating the expression of catalase, the oldest known and first discovered antioxidant enzyme, are not completely elucidated.
Catalase: A critical node in the regulation of cell fate
2023年4月1日 — Catalase (CAT) is a core antioxidant enzyme in most organisms that catalyses the decomposition of hydrogen peroxide (H 2 O 2), thereby controlling the abundance of this essential cellular signalling molecule.
Molecule of the Month: Catalase - RCSB: PDB-101
Catalases are some of the most efficient enzymes found in cells. Each catalase molecule can decompose millions of hydrogen peroxide molecules every second. The cow catalase shown here (PDB entry 8cat ) and our own catalases use an iron ion to assist in this speedy reaction.
Characteristics Of A Catalase Enzyme - Sciencing
2019年3月8日 — The key catalase function is protecting cells from hydrogen peroxide (H 2 O 2) molecules by converting them to oxygen (O 2) and water (H 2 O). H 2 O 2 can damage DNA. Catalase is formed by four individual parts, or monomers, that wrap into a …
