一般說明
氯过氧化物酶是由真菌分泌的一种含血红素的糖蛋白。氯过氧化物酶(CPO)是一种以高铁血红素IX为辅基的胞外血红素糖酶。
應用
在 131 I 离子标记研究、蛋白质溴化和 36 Cl 标记大分子的长期分离程序中，可作为乳过氧化物酶的有效替代品。
它已被用于研究聚合物纳米反应器中的生物催化氧化。
氯过氧化物酶（来自Caldariomyces fumagois）在131I标记和蛋白质溴化和长期分离程序的大分子36Cl标记中，可作为乳过氧化物酶的有效替代品。 它已用于研究聚合物纳米反应器中的生物催化氧化。
生化／生理作用
氯过氧化物酶(CPO)由真菌分泌产生，具有广谱的化学反应性。它是一种依赖过氧化物的氯化酶，也催化过氧化物酶的脱氢、过氧化氢酶的过氧化氢(H2O2)降解和细胞色素P450的氧原子插入反应。该酶具有类似于细胞色素P450的磁性和光谱特性。来源于Caldariomyces fumago的氯过氧化物酶可氯化多环芳烃(PAH)等芳香烃类化合物。氯过氧化物酶具有潜在健康风险，因其致癌和致突变性而又在环境中广泛散布。
