Magnetic field-assisted blanching enhances sulforaphane synthesis in broccoli florets, revealed by UPLC-ESI-QTRAP-MS/MS [PDF]

Food Chemistry: X
Sulforaphane (SF) is generated from glucoraphanin hydrolysis catalyzed by endogenous myrosinase in Brassicaceae vegetables such as broccoli, with blanching critical to maximize SF formation.

Long-term methyl jasmonate exposure triggers COI1-independent induction of myrosinases TGG1 and TGG2 in Arabidopsis [PDF]

Frontiers in Plant Science
Plants are constantly subjected to stresses such as herbivore attacks, which continuously activate the jasmonic acid (JA) signaling pathway in nature.

Studies on Myrosinase. Part II

Journal of the agricultural chemical society of Japan, 1959
(1)動物(ほらがい肝臓)ミロスルファターゼはシニグリン, tetramethylsinigrin, tetraacetylsinigrinの何れにも作用してその硫酸エステル結合を切る事,之に対し植物(白からし)ミロシナーゼは,シニグリンには作用してその硫酸エステル結合及びチオグルコシッド結合を切るが, tetramethylsinigrin, tetraacetylsinigrinには全く作用しない事を知った. (2)阻害剤に対する性質も,植物ミロシナーゼのミロスルファターゼ作用と,動物ミロスルファターゼとでは,可成り異る事を明かにした.

Hijacking the Mustard-Oil Bomb: How a Glucosinolate-Sequestering Flea Beetle Copes With Plant Myrosinases

Frontiers in Plant Science, 2021
Myrosinase enzymes play a key role in the chemical defense of plants of the order Brassicales. Upon herbivory, myrosinases hydrolyze the β-S-linked glucose moiety of glucosinolates, the characteristic secondary metabolites of brassicaceous plants, which ...

Arabidopsis myrosinases link the glucosinolate-myrosinase system and the cuticle [PDF]

Scientific Reports, 2016
AbstractBoth physical barriers and reactive phytochemicals represent two important components of a plant’s defence system against environmental stress. However, these two defence systems have generally been studied independently. Here, we have taken an exclusive opportunity to investigate the connection between a chemical-based plant defence system ...

Studies on Fungous Myrosinase

Agricultural and Biological Chemistry, 1969
In order to obtain fungous myrosinase, Aspergillus sydowi IFO 4284 was cultured on a medium containing mustard seed extract for 2 weeks. Myrosinase in the broth was purified about 150 fold by precipitation with ammonium sulfate and chromatography on DEAE-cellulose and DEAE-Sephadex.

Microorganisms—An Effective Tool to Intensify the Utilization of Sulforaphane

Foods, 2022
Sulforaphane (SFN) was generated by the hydrolysis of glucoraphanin under the action of myrosinase. However, due to the instability of SFN, the bioavailability of SFN was limited. Meanwhile, the gut flora obtained the ability to synthesize myrosinase and

A Comparison of Myrosinase Activity and Stability in Fresh Broccoli (B. oleracea var. Italica) and Brown Mustard (B. juncea) Seeds

Turkish Journal of Agriculture: Food Science and Technology, 2020
The effects of temperature and pressure processing on myrosinase extracted from fresh broccoli and brown mustard seed was studied. Brown mustard seeds had higher myrosinase activity (2.75 un/mL) than fresh broccoli (0.58 un/mL).
