Myrosinase

Myrosinase (or thioglucoside glucohydrolase) 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 shares 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. Its known biological function is to catalyze the hydrolysis of a class of compounds called glucosinolates.
