  Myrosinase (thioglucosidase, EC 3.2.1.147) is the enzyme responsible for the hydrolysis of glucosinolates (GLs). In plant tissue, myrosinase and GLs are sequestered in separate cellular compartments. As a result of cell disruption, e.g., after pathogen attack or on chopping or grinding during food preparation, the myrosinase comes into contact with GLs and catalyzes the hydrolysis of thioglucosidic bond in GL structure. Consequently,...

  In the process of biofumigation typically natural compounds present in Brassicaceae family are used to combat pests and protect crops. Glucosinolates, sulfur-containing secondary metabolites found in Brassica plants, are hydrolized by the enzyme myrosinase (β-thioglucosidase, EC 3.2.3.1) with the liberation of degradation products such as isothiocyanates, nitriles, thiocyanates and epithionitriles. Isothiocyanates are the most...
