General description
Human catalase is a member of the monofunctional heme-containing catalases. It is an intracellular enzyme located at higher concentrations in the liver, erythrocytes, and kidney. Catalase is a homo-tetrameric protein and comprises amino acid residues, one heme group that is iron III protoporphyrin IX, and a nicotinamide adenine dinucleotide phosphate (NADPH) molecule. It is a ubiquitous enzyme found in most aerobic organisms. The catalase (CAT) gene is located on the human chromosome at 11p13.
Application
- to prevent reoxidation of reduced cytochrome c by H2O2 while measuring the production of superoxide with cytochrome C.
- as a component of the imaging buffer for stochastic optical reconstruction microscopy (STORM) imaging of human skin fibroblasts
- as a component of the gloxy mix for single-molecule imaging

Oxidative stress is mediated, in part, by reactive oxygen species produced by multiple cellular processes and controlled by cellular antioxidant mechanisms such as enzymatic scavengers or antioxidant modulators. Free radicals, such as reactive oxygen species, cause cellular damage via cellular.
