Descrição geral
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.
Catalase (CAT) is an antioxidant enzyme, encoded by the CAT gene family. The enzyme is ubiquitously expressed in most of the aerobic organisms.
Aplicação
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.
Ações bioquímicas/fisiológicas
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.
Definição da unidade
1 U corresponds to the amount of enzyme which decomposes 1 μmol H2O2 per minute at pH 7.0 and 25 °C

Catalase is one of the firsts in every realm of biological sciences. At the same time it also has a number of unusual features. It has one of the highest turnover numbers of all enzymes. It is essential for neutralizing
Physiological mechanisms of adaptive developmental plasticity in Rana temporaria island populations.
Pablo Burraco et al.
BMC evolutionary biology, 17(1), 164-164 (2017-07-08)
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

PloS one, 8(12), e84266-e84266 (2013-12-21)
Many amphibian species exploit temporary or even ephemeral aquatic habitats for reproduction by maximising larval growth under benign conditions but accelerating development to rapidly undergo metamorphosis when at risk of desiccation from pond drying. Here we determine mechanisms enabling developmental

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
