Myrosinase (EC 3.2.1.147 thioglucoside glucohydrolase sinigrinase and sinigrase) is a family of enzymes involved in plant defense against herbivores. The three-dimensional structure has been elucidated and is available in the PDB (see links in the infobox).A member of the glycoside hydrolase family myrosinase possesses several similarities with the more ubiquitous O-glycosidases.However myrosinase is the only known enzyme found in nature that can cleave a thio-linked glucose.
