Indication of thioglucosidase activity in extracts of Neisseria gonorrhoeae
Annales De L'Institut Pasteur Microbiologie, 1987The recent demonstration of a host-derived inducer of gonococcal resistance to complement-mediated killing by human serum in purified serum and red blood cell fractions, which contained small glucopeptides with cysteine as one of the constituent amino acids, prompted an investigation of Neisseria gonorrhoeae for thioglucosidase activity.

Properties of Brussels sprouts thioglucosidase
Food Chemistry, 1989Abstract Some important properties of Brussels sprouts thioglucosidase have been studied using ammonium sulphate precipitates. The enzyme activity followed Michaelis-Menten kinetics with sinigrin as substrate. Ascorbic acid was shown both to activate and to inhibit the thioglucosidase with an optimum activity at 10 − 2 M ascorbate.

Localization of benzyl glucosinolate and thioglucosidase in Carica papaya fruit
Phytochemistry, 1973Abstract Macerated papaya seeds and pulp contained benzyl isothiocyanate, produced by the enzymatic hydrolysis of benzyl glucosinolate by thioglucosidase. The substrate and enzyme were localized in different areas. In mature papaya seeds, thioglucosidase was found in sarcotestae but not in endosperms, while the reverse was true for benzyl ...

Synthesis of 2-deoxy-2-fluoro-glucotropaeolin, a thioglucosidase inhibitor
Carbohydrate Research, 1997Abstract SN2-Displacement of the anomeric bromine atom in 3,4,6- tri -O- acetyl-2-deoxy-2-fluoro-α- d -glucopyranosyl bromide with the tetrabutylammonium salt of triphenylmethanethiol afforded the corresponding trityl 1-thio-β- d -glucoside which led to the fully protected S- acetyl-2-fluoro-1-thio-β- d -glucose derivative, and ...

Abstract A β-thioglucosidase capable of hydrolyzing mustard oil glucosides is of rare occurrence in fungi. Aspergillus sydowi QM 31c is a good source of the enzyme. The fungal enzyme resembles mustard seed myrosinase. Both enzymes degrade sinigrin producing glucose, KHSO4, and allyl isothiocyanate.

Abstract As the hydrolysis product of radish thioglucoside catalyzed by thioglucosidase, sulforaphene (SFE) is a kind of functional ingredient with broad market prospects in virtue of its strong anti-oxidation, anti cell mutation, anti-cancer, antibacterial and herbicidal activities.

Glucosyl transfer by beta-thioglucosidase
Phytochemistry, 1968Abstract The β-thioglucosidase of black mustard, Brassica nigra, has been shown to carry out the transfer of a d -glucopyranosyl residue to an acceptor other than water. This appears to be the first reported example of transglycosylation catalyzed by a thioglucosidase system. The enzyme was partially purified by salt fractionation and the conditions

Abstract The ability of some naturally occurring polyhydroxyalkaloids to inhibit the hydrolysis of the glucosinolates, sinigrin (allylglucosinolate) and progoitrin [(2R)-2-hydroxybut-3-enylglucosinolate], by thioglucosidases from mustard and the cabbage aphid, Brevicoryne brassicae, was assessed. Several compounds, in particular castanospermine, DMDP

Microwave inactivation of thioglucosidase in intact crambe seeds
JAOCS, Journal of the American Oil Chemists' Society, 1978AbstractOptimum conditions for microwave inactivation of thioglucosidase in whole crambe seeds(Crambe abyssinica Hochst.) were investigated. Whole crambe seeds were left at 7% moisture or tempered to between 10 and 20% moisture contents prior to exposure to various microwave power inputs for 38 sec under controlled conditions.
