组织蛋白酶D是一种与组织分解相关的雌激素调节蛋白。组织蛋白酶D水平与淋巴结阴性和淋巴结阳性类型的复发性乳腺癌呈正相关。此外，组织蛋白酶D与阿尔茨海默氏症斑块中淀粉样蛋白的形成有关。由于香烟烟雾会增加组织蛋白酶D的活性，这种酶可能会导致吸烟者的肺组织损伤。 活性：>=300单位/毫克蛋白质。一个单位被定义为消化血红蛋白释放肽的酶的量，这些肽可溶于10%TCA。通过在37°C下每60分钟增加1.0的A280来测量反应。底物：酸变性血红蛋白，pH 1.8（反应混合物中0.2%）。缓冲液：100 mM甲酸盐，pH 3.3。 Cathepsin D is an estrogen-regulated protein associated with tissue breakdown. Levels of cathepsin D have been positively correlated with recurring breast cancers of both node-negative and node-positive types. Additionally cathepsin D has been associated with amyloid formation in Alzheimer's plaques. As cathepsin D activity is increased by cigarette smoke, the enzyme may contribute to lung tissue damage in smokers. Activity: >=300 units per mg protein. One unit is defined as the amount of enzyme that digests hemoglobin-releasing peptides which are soluble in 10% TCA. The reaction is measured by an increase of an A 280 of 1.0 per 60 minutes at 37°C . Substrate: acid denatured hemoglobin, pH 1.8 (0.2% in reaction mixture). Buffer: 100 mM formate, pH 3.3.
