Catalase Native Protein | CAT native protein

Catalase protein

Cat. Num. AAA537842

• Applications: User optimized
• Synonyms: Catalase; Catalase protein; CAT; MGC138422; MGC138424; Cs1; Cas 1; CAT native protein

• Host: Human
• Form/Format: Frozen in 50mM Tris buffer, pH 8.0
• Sequence Length: 527

• Applicable Applications for CAT native protein: User optimized
• Source Note: Human whole blood
• Protein Type: Native
• Biological Significance: Catalase is a common enzyme found in nearly all living organisms that are exposed to oxygen, where it functions to catalyze the decomposition of hydrogen peroxide to water and oxygen. Catalase is a tetramer of four polypeptide chains, each over 500 amino acids long. It contains four porphyrin heme (iron) groups that allow the enzyme to react with the hydrogen peroxide. The optimum pH for human catalase is approximately 7.
• Biohazard Information: Donor samples were tested and found to be negative for HBsAg, anti-HCV, anti-HBc, and negative for anti-HIV 1 & 2. Nonetheless caution should be used when handling this material as there is a margin of error in all tests.
• Dry Ice Shipment: Extra charge fee may add to your shipping cost as dry ice is required to ship this product.
• Preparation and Storage: Aliquot and store at -70 degree C or lower. Avoid repeated freeze/thaw cycles.

NCBI Description

This gene encodes catalase, a key antioxidant enzyme in the bodies defense against oxidative stress. Catalase is a heme enzyme that is present in the peroxisome of nearly all aerobic cells. Catalase converts the reactive oxygen species hydrogen peroxide to water and oxygen and thereby mitigates 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 diabetes, asthma, Alzheimer's disease, systemic lupus erythematosus, rheumatoid arthritis, and cancers. Polymorphisms in this gene have been associated with decreases in catalase activity but, to date, acatalasemia is the only disease known to be caused by this gene. [provided by RefSeq, Oct 2009]

Uniprot Description

Catalase: Occurs in almost all aerobically respiring organisms and serves to protect cells from the toxic effects of hydrogen peroxide. Promotes growth of cells including T-cells, B-cells, myeloid leukemia cells, melanoma cells, mastocytoma cells and normal and transformed fibroblast cells. Homotetramer. Belongs to the catalase family.
