Background: Catalase (CAT) is an important enzyme that degrades H2O2 into H2O and O2. To obtain an efficient catalase, in this study, a new strain of high catalase-producing Serratia marcescens, named FZSF01, was screened and its catalase was purified and... see more

The catalase is found out in all aerobic organisms. At catalyses significant metabolic reaction of decomposition of Ð2О2 intomolecular oxygen and water. Catalase is applied in medicine as antioxidizer at various diseases, to remove the peroxi... see more

 Peppermint oil is one of the essential oils with antioxidant activity that can reduce levels of reactive oxygen species (ROS). An acute single bout of eccentric exercise (ASBEE) is an acute exercise activity that can lead to increased ROS and cause ... see more

Enzyme catalase is characterized by the high catalytic activity, almost doesn’t need activation energy, reaction velocity of this enzyme limits not only the velocity of substrate diffusion to the active center. The action mechanism of catalase is in disin... see more

Environments containing significant concentration of NaCl such as salt lakes harbor extremophiles microorganisms which have a great biotechnology interest. To explore the diversity of Bacteria in Chott Tinsilt (Algeria), an isolation program was... see more

The catalase enzyme is analyzed under different conditions in order to get a better understanding of its function, purpose and benefit to organisms. This enzyme resides in all living organisms that have exposure to oxygen. It uses hydrogen peroxide (H2O2)... see more

Through genetic engineering technology, catalase (CAT) and superoxide dismutase (SOD) have been separately fused to an elastin-like polypeptide (ELP). Thus, the enzymes can be purified through phase transition. Hexadecylamine-modified poly(aspartic acid) ... see more

Cwynar Anna, Olszewska-Slonina Dorota, Pukownik Ewelina. The effect of oxidative modifications of amino acid residues in the active center of tyrosinase on the process of graying = Wplyw oksydacyjnych modyfikacji reszt aminokwasowych w centrum aktywnym ty... see more

In this study, we investigated the relationship between catalase activity and H2O2-induced hormetic response in budding yeast S. cerevisiae. In general, our data suggest that: (i) hydrogen peroxide induces hormesis in a concentration- and time-dependent m... see more
