Environmental stimuli such as UV, pathogen attack, and gravity can induce rapid changes in hydrogen peroxide (H2O 2) levels, leading to a variety of physiological responses in plants. Catalase, which ...

Catalase enzymes play a pivotal role in cellular defence by decomposing hydrogen peroxide into water and oxygen, thereby mitigating oxidative stress. These oxidoreductases are ubiquitously found ...

The COVID-19 pandemic has spread across the whole world, causing over 13.75 million confirmed infections and over 589,000 deaths until now. Many broad-spectrum antiviral drugs have been tried in an ...

Photosynthesis and the Warburg effect (O2 inhibition of photosynthesis) were evaluated in preparations of intact spinach chloroplasts enriched with varying amounts of lysed chloroplasts. Increasing ...

Peroxidases are enzymes that break down hydrogen peroxide in organisms. Since their discovery in 1998, the electron source of ...

Acatalasemia is a metabolic condition (inborn error of metabolism) associated with a very low catalase activity in erythrocytes. Catalase is an antioxidant enzyme ...
