The structure of bovine liver catalase determined from a single crystal at 3.2 A resolution by MicroED, is reported.
These maps demonstrate that it is indeed possible to build atomic models from such crystals and even to determine the charged states of amino acid residues in the Ca(2 (show CA2 Proteins)+)-binding sites of Ca(2+)-ATPase and that of the iron atom in the heme in catalase.
Data indicate compatible osmolytes, proline, xylitol, and valine destabilize the denatured form of the catalase enzyme and, therefore, increase its disaggregation and thermal stability.
Flavonoid inhibition of catalase activity is, at least partially, due to the formation of hydrogen bonds between catalase and the flavonoid.
Comparison of deoxyferrous and oxyferrous complexes of cAOS and MAP with bovine liver catalase elucidates unresolved mechanistic questions in the catalytic cycles of these enzymes
Catalase is not influenced by the solvent during the catalytic reaction, which represents a lower energy barrier to be crossed in the overall energetics of the reaction, a fact that contributes to the high turnover rate of catalase.
At room temperature (25.0 degrees C) and higher, the addition of high concentrations of polymer is found to significantly enhance the affinity of SOD for catalase.

The present study determined that ARE, CLP (show CALML3 Proteins), CAT, and MPO (show MPO Proteins) levels are different between the pediatric patients with sepsis and healthy controls. ARE level can be a potent biomarker for sepsis in critical patients in intensive care units.

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.
