Description
Myrosinases are present in many bacteria, fungi, and edible plants, including those of the Brassicaceae (Cruciferae) family. The enzyme hydrolyzes the S-glucosidic bond of a glucosinolate substrate to form an unstable aglycone that rearranges with the loss of sulfate primarily to the isothiocyanate, though thiocyanates and nitriles are also formed. Many of the isothiocyanate products of aliphatic and aromatic glucosinolates have cancer chemopreventive properties.
Abbr
Myrosinase, Native (Sinapis alba)
Source
Sinapis alba (white mustard) seed
Applications
Thioglucosidase has been used in a study to assess Brassica species screening for glucosinolate content. Thioglucosidase has also been used in a study to investigate a negative regulatory role for auxin in sulphate deficiency response in Arabidopsis thaliana.
Product Overview
Thioglucosidase research has f ocused mainly on the cruciferous crops due to their economic importance and cancer preventive benefits.
