Cruciferous vegetables are rich in glucosinolates that can be hydrolyzed by myrosinase into isothiocyanates (ITCs) with significant anticancer properties. In the absence of bacterial myrosinase, glucosinolates are excreted from the body in their inactive forms. However, the mechanisms underlying the bacterial breakdown of glucosinolates are not well understood. Here, we investigated the mechanism and enzymes involved in glucosinolate breakdown by the probiotic microorganism
