概述

辣根过氧化物酶已用于:粪便淀粉分析通过Trinder法测定血浆葡萄糖水平孵育阿魏酰基阿拉伯糖基木聚糖组分并评估氧化偶联检测糖蛋白应用:

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。

Horseradish peroxidase is isolated from horseradish roots (Amoracia rusticana) and belongs to the ferroprotoporphyrin group of peroxidases. HRP is a single chain polypeptide containing four disulfide bridges. It is a glycoprotein containing 18% carbohydrate. The carbohydrate composition consists of galactose, arabinose, xylose, fucose, mannose, mannosamine, and galactosamine depending upon the specific isozyme. Its molecular weight (~44 kDa) includes the polypeptide chain (33,890 Daltons), hemin plus Ca2+ (~700 Daltons), and carbohydrate (~9,400 Daltons). At least seven isozymes of HRP exist. The isoelectric point for horseradish peroxidase isozymes ranges from 3.0 - 9.0.

Application:

Peroxidase from horseradish has been used:
  • in fecal starch analysis
  • to measure plasma glucose levels by Trinder method
  • to incubate feruloylated arabinoxylan fractions and also to evaluate oxidative coupling
  • in the detection of glycoproteins

生化机理
HRP易与过氧化氢(H2O2)结合,所得[HRP-H2O2]配合物可氧化各种氢供体。最佳pH为6.0-6.5,酶在5.0-9.0的pH范围内最稳定。HRP可以通过几种不同的方法与抗体缀合,包括戊二醛、高碘酸盐氧化、通过二硫键以及通过氨基和巯基定向交联剂。它比酶标签β-半乳糖苷酶和碱性磷酸酶更小、更稳定。因此,它是最理想的标签。而且,糖基化使其非特异性结合较低。它还用于测定溶液中的葡萄糖 和过氧化物 。已知叠氮化钠、氰化物、L-胱氨酸、重铬酸盐、亚乙基硫脲、羟胺、硫化物、钒酸盐、对氨基苯甲酸和Cd2+、Co2+、Cu2+、Fe3+、Mn2+、Ni2+、Pb2+离子可抑制酶活性。当与底物一起孵育时,辣根过氧化物酶可产生标记分子的有色荧光或发光衍生物,从而进行定量。
