Anti-Catalase

AB0245-200

Anti-Catalase

Goat polyclonal antibody to Catalase – peroxisome marker. Catalase is a tetramer consisting of 4 equal subunits each with a 60 kDa molecular weight. It is an antioxidant enzyme present in the peroxisomes of aerobic cells and protects cells from the toxic effects of hydrogen peroxide. Oxidative stress is hypothesized to play a role in the development of many chronic or late-onset diseases such as Alzheimer's disease, asthma, cancer, diabetes, rheumatoid arthritis, auto-immune diseases, etc.

Anti-Catalase Antibody [JM11-12]

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. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS). Catalase has one of the highest turnover numbers of all enzymes; one catalase molecule can convert millions of hydrogen peroxide molecules to water and oxygen each second. Catalase is a tetramer of four polypeptide chains, each over 500 amino acids long. It contains four iron-containing heme groups that allow the enzyme to react with hydrogen peroxide. The optimum pH for human catalase is approximately 7, and has a fairly broad maximum: the rate of reaction does not change appreciably between pH 6.8 and 7.5. The pH optimum for other catalases varies between 4 and 11 depending on the species. The optimum temperature also varies by species.
