General description
乳过氧化物酶是存在于牛奶中的主要酶，属于过氧化物酶家族。它同时存在于植物和动物中。其酶结构包含由612个氨基酸残基组成的多肽链。
Application
牛奶中的过氧化物酶用作牛奶过氧化物酶标准品，研究在原料乳中存在乳过氧化物酶时H2O2对抑制金黄色葡萄球菌生长的作用。它也用于乳过氧化物酶介导的碘化，以制备放射性标记肽。
Biochem/physiol Actions
乳过氧化物酶催化过氧化氢与碘化物的氧化反应生成碘。该活性提供了一种温和的特异性氯胺 T 替代物，用于蛋白质和 DNA 的放射性碘化反应。
乳过氧化物酶通过灭活多种微生物来促进牛奶的抗菌系统。这种乳过氧化物酶介导的抗菌系统也见于人类分泌物，如泪液、唾液和乳汁。乳过氧化物酶通过释放H2O2催化分子氧化。产物具有抗菌活性。
Analysis Note
Lowry法测蛋白。
Other Notes
在25℃、pH 5.5条件下，一个单位可氧化1.0 μmM 2,2′-联氮基-双(3-乙基苯并噻唑啉-6-磺酸)。
