一般描述
研究领域：细胞信号传导
过氧化氢酶（CAT）是一种抗氧化酶，由CAT基因家族编码。该酶在大多数好氧生物中普遍存在。
过氧化氢酶（CAT）是一种抗氧化酶，由CAT基因家族编码。该酶在大多数好氧生物中普遍存在。
应用
裂解溶壁微球菌的过氧化氢酶已被用于通过体外生物催化级联消除糖类似物合成过程中过量的过氧化氢产生。它也被用作通过间接测量催化活性来评估氧化应激的标准。
生化/生理作用
过氧化氢酶能迅速将过氧化氢转化为氧气和水。它表现出抗氧化活性，并引发对活性氧（ROS）的防御机制。过氧化氢酶在自然界以及纺织、制药和乳制品等各种行业中起着中和有害过氧化氢的作用。微小球菌赖氨酸过氧化氢酶是一种含血红素的蛋白质。过氧化氢酶与参与过氧化氢（H2O2）处理的多种关键细胞系统一起，在调节细胞氧化还原平衡和辅助细胞和细胞间信号传递方面起着关键作用。

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

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
