Descrizione generale

Research Area: Cell Signaling

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.

Applicazioni

Catalase acts as a natural antioxidant to study the roles of reactive oxygen species in gene expression and apoptosis. It has also been used to protect against oxidative damage to proteins, lipids, and nucleic acids. Industrially, catalzes have been used to remove hydrogen peroxide added to milk and cheese, in textile bleaching, and to examine its positive effects on the viability of DNA-repair mutants of E. coli.

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

Azioni biochim/fisiol

Catalase, an antioxidant enzyme found in all aerobic organisms, catalyzes the degradation of hydrogen peroxide, a byproduct of metabolic processes, into less harmful water and oxygen. It can also react with alkylhydrogen peroxides, such as methylperoxide and ethylperoxide and the second H2O2 molecule can be replaced by methanol, ethanol, propanol, formate and nitrate as a hydrogen donor. Catalase enzyme uses either iron (Fe) or manganese (Mn) as cofactor, and are classified as Fe-CAT or Mn-CAT.

Definizione di unità

One unit will decompose 1.0 micromole of hydrogen peroxide per minute at pH 7.0 and 25 deg C, while the hydrogen peroxide concentration falls from 10.3 to 9.2 millimolar.

Determining how microtubules (MTs) are nucleated is essential for understanding how the cytoskeleton assembles. While the MT nucleator, γ-tubulin ring complex (γ-TuRC) has been identified, precisely how γ-TuRC nucleates a MT remains poorly understood. Here, we developed a single molecule

To establish the microtubule cytoskeleton, the cell must tightly regulate when and where microtubules are nucleated. This regulation involves controlling the initial nucleation template, the γ-tubulin ring complex (γTuRC). Although γTuRC is present throughout the cytoplasm, its activity is restricted

An elevated intracellular NADH:NAD+ ratio, or 'reductive stress', has been associated with multiple diseases, including disorders of the mitochondrial electron transport chain. As the intracellular NADH:NAD+ ratio can be in near equilibrium with the circulating lactate:pyruvate ratio, we hypothesized that
