General description
Catalase is encoded by the gene mapped to human chromosome 11p13. Mammalian catalase is an antioxidant enzyme and is a member of hydroperoxidase family). The active enzyme is homotetrameric in nature.
Catalase from bovine liver is a tetramer consisting of 4 equal subunits each with a 60 kDa molecular weight. Each of these subunits contains iron bound to a protoheme IX group. The enzyme will also strongly bind to NADP, where NADP and the heme group are within 13.7 angstroms.
Application
- as a component of gloxy, which is one of the most popular oxygen-scavenging systems.
- in single molecule fluorescence resonance energy transfer (FRET) measurements.
- in cytochrome-C oxidase (COX) histochemistry to study the role of mitochondrial uncoupling protein 2 (UCP2) in limiting oxidative stress during glaucoma.
- to pre-treat slide chambers for total internal reflection fluorescence (TIRF) microscopy.
- in quantifying hydrogen peroxide release.
- to help minimize the effects of reactive oxygen species (ROS) in cooperativity assay for studying doublecortin and microtubule interaction.
Catalase from bovine liver may be used:
- to prepare H2O2-O2 based biocathode for applications in glucose biofuel cells
- to study the kinetic properties and storage stability of catalase immobilized on to florisil
- in glutathione-mediated superoxide generation in an aqueous solution
