General description

Research area: Cell Signaling

Catalase (CAT) is an antioxidant enzyme, encoded by the CAT gene family. The enzyme is ubiquitously expressed in most of the aerobic organisms.

Application

Catalase from Micrococcus lysodeikticus has been used to eliminate excess of hydrogen peroxide production during sugar analog synthesis by in vitro biocatalytic cascade. It has also been used as a standard to evaluate oxidative stress by indirectly measuring catalytic activity.

Biochem/physiol Actions

Catalase rapidly converts hydrogen peroxide to oxygen and water. It exhibits antioxidant activity and elicits a defense mechanism against reactive oxygen species (ROS). Catalase plays a role in neutralizing noxious hydrogen peroxide in nature as well as in various industries such as textile, pharma, and dairy. Micrococcus lysodeikticus catalase is a heme-containing protein.Catalase, along with various key cellular systems involved in hydrogen peroxide (H2O2) processing, plays a key role in regulating cellular redox balance and aids in cellular and intercellular signaling.

Unit Definition

1 U corresponds to the amount of enzyme which decomposes 1 μmol H2O2 per minute at pH 7.0 and 25 °C

Adaptive plasticity is essential for many species to cope with environmental heterogeneity. In particular, developmental plasticity allows organisms with complex life cycles to adaptively adjust the timing of ontogenetic switch points. Size at and time to metamorphosis are reliable fitness

Organisms are exposed to multiple environmental factors simultaneously to which they often respond behaviorally, morphologically and/or physiologically. Amphibian larvae are quite plastic and efficiently adjust their phenotype and physiology to the reigning local conditions. Here we tested whether the combination
