Application

辣根过氧化物酶已被用于脱氢聚合物 (DHP) 的研究，以研究单寡聚物偶联机制。 它还被用来通过创建辣根过氧化物酶模拟DNAzyme来帮助开发用于microRNA（miRNA）检测的比色方法。

Biochem/physiol Actions

已证明辣根过氧化物酶可催化多种物质的聚合，包括对乙酰氨基酚和腰果酚。

Analysis Note

RZ(Reinheitszahl)是指溶于去离子水中的酶(0.5–1.0 mg/ml)的吸光度比值A403/A275 。 它是血红素含量的量度，而不是酶活性。 即使是RZ值较高的制剂也可能具有较低的酶活性。

Disclaimer

在低 pH 值和较高温度下保持活性。

General description

辣根过氧化物酶是从辣根（Amoracia rusticana）中分离出来的，属于过氧化物酶的铁原卟啉基团。HRP是含有四个二硫键的单链多肽。它是一种含有18%碳水化合物的糖蛋白。碳水化合物由半乳糖、阿拉伯糖、木糖、岩藻糖、甘露糖、甘露糖胺和半乳糖胺组成，具体取决于特定同工酶。其分子量（约44 kDa）包括多肽链（33,890道尔顿）、氯化血红素加Ca2+ （约700道尔顿）和碳水化合物（约9,400道尔顿）。至少存在7种HRP同工酶。 辣根过氧化物酶同工酶的等电点范围为3.0-9.0。

Other Notes

一个连苯三酚单元将在20℃、pH 6.0条件下，在20秒内从连苯三酚形成1.0mg的红棓酚。

Horseradish peroxidase catalyzed the polymerization of acetaminophen. Addition of reduced glutathione (GSH) to reaction mixtures resulted in decreased polymerization and formation of minor amounts of GSH-acetaminophen conjugates. The conjugates were identified as 3-(glutathion-S-yl)acetaminophen and 3-(glutathion-S-yl)diacetaminophen. Horseradish peroxidase also catalyzed polymerization
