Cyanogenic Glycosides and Glucosinolates are nitrogen containing secondary metabolites in plants. Following are some statements regarding the action of Cyanogenic Glycosides and Glucosinolates;

a) Cyanogenic Glycosides release the poison hydrogen cyanide by the action of enzyme known as Hydroxynitrile lyase

b) Release of the mustard-smelling volatiles from glucosinolates is catalyzed by a hydrolytic enzyme, called a thioglucosidase or myrosinase

c) substerate for Glycosidase is Cyanogenic glycoside and Thioglucosidase is Aglycone

d) Like cyanogenic glycosides, glucosinolates are stored in the intact plant separately from the enzymes that hydrolyze them, and they are brought into contact with these enzymes only when the plant is crushed

The low expression level of cry genes seems to be due to the presence in them of sequences not commonly found in plant coding regions. Such as
(1) Localized A+T-rich regions resembling plant intrans 
(2) 18 potential plant polyadenylation signal sequences 
(3) 13 ATTTA sequences, which destabilize mRNA
(4) Codons that are rarely used in plants
