The hydrolyzing enzyme, myrosinase (a thioglucosidase), is stored in different cells than its substrates. While myrosinase-containing cells are mostly glucosinolate-free, the so-called sulfur-rich cells (or S-cells) contain high concentrations of glucosinolates.

Benzoxazinoids, especially 2,4-dihydroxy-1,4-benzoxazin-3-one (DIBOA) and its derivative 2,4-dihydroxy-7-methoxy-1,4-benzoxazin- 3-one (DIMBOA), are usually stored in the vacuole as glycosides coupled to d-glucose.
