Thioglucosidase activity

Myrosinase has thioglucosidase activity. The myrosinase-mediated degradation of glucolimnanthin yields an intermediate aglycone that rearranges to form... 

Enzyme preparations of three Pieris species each contained B-thioglucosidase activity, a fact previously reported (36), and each inhibited hydrolysis in one or more combinations with a plant enzyme-substrate system. These data are being quantified and extended to include insect/preferred host-plant pairs. 

An induced molecular species from Stachybotrys atra displayed j -D-xylo-sidase, jS-D-glucosidase, and )S-D-thioglucosidase activities. ... 

In conclusion, it seems that myrosinase activity is relatively easy (in evolutionary time) to acquire from p-glucosidases. It will be a fascinating challenge to pin down the exact molecular alterations that are responsible for the transition from P-[OJ-glucosidase to p-[S]-thioglucosidase. 

A certain measure of control of the goitrogenic activity of meals is achieved by manipulating the pretreatment of the seed before extraction so as to ensure the earliest possible destruction of myrosinase. Such control is only partial, since bacterial thioglucosidases produced in the gut may hydrolyse residual glucosinolate in the meal.
