Myrosinase Activity in Soil Extracts
Soil Science Society of America Journal, 1996Abstract Myrosinase (β‐thioglucoside glucohydrolase; EC 3.2.3.1) catalyzes the hydrolysis of glucosinolates to form a variety of potential allelochemicals. Although these allelochemicals may exert an influence on soil‐borne organisms, the extracellular preservation of plant‐derived myrosinase in soil has not been ...

Myrosinase isoenzymes are known to be encoded by two different families of genes denoted MA and MB. Nucleotide sequence analysis of a Brassica napus genomic clone containing a gene for myrosinase revealed it to be a pseudogene of the MA family. The gene spans more than 5 kb and contains at least 12 exons. The exon sequence of the gene is highly similar

Abstract Myrosinases (EC 3.2.3.1) are a group of isoenzymes present in Cruciferaes which catalyze the hydrolysis of glucosinolates. The myrosinases from rapeseed (Brassica napus L.) have been purified and the main component isolated and characterized.

Biochimica et Biophysica Acta (BBA) - Enzymology, 1973
A comparative study was performed on some enzymatic properties of myrosinase isoenzymes (thioglucoside glucohydrolases, EC 3.2.3.1) from white mustard seed (Sinapis alba) and rapeseed Brassica napus). The investigation comprised the determination of pH optima, temperature maxima and the enzymatic stabilities of the isoenzymes, when temperature, pH ...

Myrosinase from roots of Raphanus sativus
Phytochemistry, 1995Abstract Two myrosinase isoenzymes ( EC 3. 2. 3. 1 ) were extracted and purified by (NH 4 ) 2 SO 4 precipitation and DEAE-cellulose and Sephadex G-200 chromatography from radish root tissues with M r s 28 800 and 58 900. The most active one (120 U mg −1 ) was identified and characterized.

AbstractThe Arabidopsis thaliana TGG1 gene encodes thioglucoside glucohydrolase (myrosinase), an enzyme catalysing the hydrolysis of glucosinolate compounds. The enzyme is involved in plant defence against some insect herbivores, and is present in species of the order Capparales (Brassicales). Nucleotide variation was surveyed by sequencing c.

Comparison of Myrosinase Activity Assays
1987Plant thioglucoside glucohydrolase (myrosinase EC 3.2.3.1) catalyzes the hydrolysis of glucosinolates to isothiocyanate, glucose and sulfate. We have purified myrosinase from white mustard seed (Sinapis alba) in high yields and with a considerable specific activity in a single step by affinity chromatography on Con-A Sepharose.

Two cDNA clones homologous to myrosinase-binding proteins (MBPs) were identified by differential display in Arabidopsis thaliana (L.) Heynh. The cDNAs (MBP1 and MBP2) correspond to two open-reading frames found in a gene cluster of seven putative MBP genes located on chromosome 1.

Total Myrosinase Activity Estimates in Brassica Vegetable Produce
Journal of Agricultural and Food Chemistry, 2014Isothiocyanates, generated from the hydrolysis of glucosinolates in plants of the Brassicaceae family, promote health, including anticancer bioactivity. Hydrolysis requires the plant enzyme myrosinase, giving myrosinase a key role in health promotion by brassica vegetables.

Characterization of a new myrosinase in Brassica napus
Plant Molecular Biology, 1995A full-length cDNA clone defining the new myrosinase gene family MC in Brassica napus was isolated and sequenced. Southern hybridization showed that the MC family probably consists of 3 or 4 genes in B. napus. MC genes are expressed in the developing seed, but not in the vegetative tissues investigated. In situ hybridizations to developing seeds showed
