一般說明
Research Area: Cell Signaling
Catalase from bovine liver is a tetramer consisting of 4 equal subunits each with a 60 kDa molecular weight. Each of these subunits contains iron bound to a protoheme IX group. The enzyme will also strongly bind to NADP, where NADP and the heme group are within 13.7 angstroms.

應用
过氧化氢酶作为天然抗氧化剂，可用于研究活性氧物质对基因表达和凋亡的作用。它还被用于保护蛋白质、脂质和核酸免受氧化损伤。 工业上，过氧化氢酶已被用于去除添加至牛奶和奶酪中以及纺织品漂白使用的过氧化氢，并用于检查其对DNA修复大肠杆菌突变体活力的阳性效应。
生化／生理作用
Catalase, an antioxidant enzyme found in all aerobic organisms, catalyzes the degradation of hydrogen peroxide, a byproduct of metabolic processes, into less harmful water and oxygen. It can also react with alkylhydrogen peroxides, such as methylperoxide and ethylperoxide and the second H2O2 molecule can be replaced by methanol, ethanol, propanol, formate and nitrate as a hydrogen donor. Catalase enzyme uses either iron (Fe) or manganese (Mn) as cofactor, and are classified as Fe-CAT or Mn-CAT.
單位定義
在pH 7.0、25摄氏度下，一个单位每分钟分解1.0微摩尔的过氧化氢，而过氧化氢的浓度则从10.3降至9.2毫摩尔。

Determining how microtubules (MTs) are nucleated is essential for understanding how the cytoskeleton assembles. While the MT nucleator, γ-tubulin ring complex (γ-TuRC) has been identified, precisely how γ-TuRC nucleates a MT remains poorly understood. Here, we developed a single molecule
