Chains	Enzyme Name	Description	Catalytic Residues
A	thioglucosidase M-CSA #460	Myronase is the enzyme responsible for the hydrolysis of a variety of plant anionic-1-thio-beta-glucosides, called glucosinolates. Sinapsis alba myrosinase is a 499 amino acid S-glucosidase which hydrolyses an S-glycosidic bond, and is closely related to the O-glucosidases. Upon hydrolysis, configuration at the anomeric centre is retained. Myrosinases are thought to be involved in defence systems developed by plants The protein fold into a (beta/alpha)8 barrel structure, forming a dimer which is stabilised by a Zn ion, and is heavily glycosylated. It is a member of the glycoside hydrolase family 1 (GH1).
