Myrosinase in Brassicaceae: the most important issue for glucosinolate turnover and food quality

Glucosinolates and their degradation products, isothiocyanates, have been widely identified by their benefits to human nutrition. Plant myrosinase, is an enzyme found in Brassicaceae family with an essential role on the glucosinolates conversion to isothiocyanates. In this review, we highlight recent progress in myrosinase, with particular emphasis on the involvement on in vivo glucosinolates turnover and the regulation during plant development and in response to environmental changes. Also, the myrosinase as influenced by some intrinsic and extrinsic factors, during postharvest and food processing such as pH, temperature, and pressure is examined as a challenge for increasing isothiocyanates bioactivity.
