一般描述
硫葡萄糖苷酶，也称为黑芥子酶，存在于不含芥子油苷的黑芥子酶细胞中。这种酶是从几种植物源中获得，例如独行菜、白芥和欧洲油菜等。
应用
白芥菜种子的硫葡萄糖苷酶用作量化黑芥子酶活性的标准并应用于植物样品硫代葡萄糖苷柱分析中。
硫代葡糖苷酶已用于评估不同芥菜物种中硫代葡萄糖苷含量的筛选研究中。 硫代葡糖苷酶也被用于调查 拟南芥（Arabidopsis thaliana）中，生长素对硫酸盐缺乏反应的负调节作用。
生化/生理作用
由于其经济重要性和癌症预防效益，对硫葡糖苷酶的研究主要集中在十字花科作物上。
黑芥子酶存在于许多细菌、真菌和可食用植物中，其中包括那些 十字花科 家族。 该酶可水解硫代葡萄糖苷底物的S-糖苷键以形成不稳定的糖苷配基，其随着硫酸盐的损失而发生重排，主要形成为异硫氰酸酯，但也可形成硫氰酸盐和腈。 许多脂族和芳族硫代葡萄糖苷的异硫氰酸酯产物具有癌症化学预防性质。
单位定义
在pH6.0，25℃条件下，一个单位每分钟可从黑介子苷中产生1.0μmole葡萄糖。

Glycoside hydrolase family 1 (GH1) members exhibit a broad substrate spectrum and play important roles in insect-plant interactions, such as the defensive β-glucosidase and β-thioglucosidase (so-called myrosinase). However, knowledge about the expression profiling and function of glycoside hydrolase family 1

Glucosinolates are found in plants of the order Brassicales and hydrolyzed to different breakdown products, particularly after tissue damage. In Barbarea vulgaris R.Br. (Brassicaceae), the dominant glucosinolate in the investigated "G-type" is glucobarbarin, (S)-2-hydroxy-2-phenylethylglucosinolate. Formation of the nitrile from glucobarbarin

Glucosinolates (GSLs), a group of compounds found in Brassica plants, are toxic to some soil-borne plant pathogens because of the toxicity of their hydrolysis products, isothiocyanates. Other phytochemicals found in Brassica plants, such as phenols and ascorbic acid, may compliment

Sulforaphane (a potent anticarcinogenic isothiocyanate derived from glucoraphanin) is widely considered responsible for the protective effects of broccoli consumption. Broccoli is typically purchased fresh or frozen and cooked before consumption. We compared the bioavailability and metabolism of sulforaphane from portions
