glucoside/glycine max

A previous study demonstrated that purified Glycine max β-glucosidase (GmBGL) could hydrolyze glucosyl isoflavone to the aglyconic form. This study reports the cloning and functional characterization of a soybean cDNA encoding the β-glucosidase. GmBGL was isolated by use of a purified soybean

A cDNA from soybean (Glycine max (L.) Merr.), GmIF7MaT, encoding malonyl-CoA:isoflavone 7-O-glucoside-6''-O-malonyltransferase, was cloned and characterized. Soybeans produce large amounts of isoflavones, which primarily accumulate in the form of their 7-O-(6''-O-malonyl-beta-D-glucosides). The cDNA

In the screening of selective DNA polymerase (pol) inhibitors, we isolated an acylated steryl glycoside, β-sitosteryl (6'-O-linoleoyl)-glucoside (compound 1), from the waste extract of soybean (Glycine max L.) oil. This compound exhibited a marked ability to inhibit the activities of eukaryotic

5,7,3',4'-Tetrahydroxyflav-2-en-3-ol 3-O-β-D-glucoside was isolated from the seed coats of immature black soybeans (Glycine max (L.) Merr.). This compound is a reduced form of cyanidin 3-O-β-D-glucoside (cyanidin 3-G) which was obtained by reaction with hydrochloric acid. The molecule has reducing

Cyanidin 3-O-beta-D-glucoside (CG) was purified from black bean seed coat and other anthocyanins were prepared from red grape skin. These anthocyanins were identified by Mass, and 1H- and 13C-NMR. The effects of four anthocyanins on cell viability in human leukemia Molt 4B cells were investigated.

Malonylated isoflavones are the major forms of isoflavonoids in soybean plants, the genes responsible for their biosyntheses are not well understood, nor their physiological functions. Here we report a new benzylalcohol O-acetyltransferase, anthocyanin O-hydroxycinnamoyltransferase, anthranilate

Anthocyanin pigments in seed coats of black soybean (Glycine max (L.) Merr.) were extracted with 1% HCl-CH(3)OH, and the crude anthocyanin extract was purified by Shepadex LH-20 and Lichroprep RP-18 open-column chromatography. Three major anthocyanins were isolated, and their chemical structures

Black soybean (Glycine max L.) has been used as a traditional medicine because its seed coat contains various natural phenolic compounds such as anthocyanins. The objective of this study was to reveal the genetic variation in the agricultural traits, phytochemicals, and antioxidant activity

Mung beans (Vigna radiata [L] Wilczek) purchased from a Spanish company as "green soybeans", showed a different phenolic composition than yellow soybeans (Glycine max cv. Merit). Isoflavones were predominant in yellow soybeans, whereas they were completely absent in the green seeds on which

Total membranes prepared from roots of soybean (Glycine max L.) seedlings have previously been shown to contain proteinaceous binding site(s) for a hepta-beta-glucoside elicitor of phytoalexin accumulation. The hepta-beta-glucoside elicitor-binding proteins have now been shown to co-migrate with a

Isoflavone conjugate-hydrolyzing β-glucosidase (GmICHG) of soybeans [Glycine max (L.) Merr.] catalyzes the specific hydrolysis of isoflavone conjugates (β-7-O-(malonyl)glucosides of isoflavones) to produce free isoflavones. In this study, changes in the transcription levels of GmICHG in the

Protoplasts were prepared from cells of soya-bean (Glycine max) suspension cultures and the plasma membrane was labelled with diazotized [G-3H]sulphanilic acid. Homogenates were fractionated by differential and isopycnic centrifugation, and membrane fractions in a density gradient were characterized

The metabolism of [2-(14)C]- and [ring-U-(14)C]2,4-dichlorophenoxyacetic acid (2,4-D) has been studied in cell suspension cultures of soybean (Glycine max L.) and wheat (Triticum aestivum L.). 2,4-D was extensively metabolized by both cultures, the rates of metabolism and the metabolite patterns

Pulsed positive ion-negative ion chemical ionization mass spectra of O-glucosyl-zeatin and -dihydrozeatin, their ribosides, and their N-9 2-cyanoethyl and 2-chloro-2-cyanoethyl derivatives are reported. By methods based on these spectra, the levels of the glucosides were determined in soybean

Two plant-originated C-glucosyltransferases (CGTs) UGT708D1 from Glycine max and GtUF6CGT1 from Gentiana triflora were accessed for glucosylation of selected flavones chrysin and luteolin. Uridine diphosphate (UDP)-glucose pool was enhanced in Escherichia coli cell cytosol by introducing
