We isolated membrane vesicles from maize (Zea mays L.) coleoptiles and identified in these vesicles a 58 kDa (pm58) and a 60 kDa (pm60) protein by photoaffinity labelling with 5-azido-[7-3H]indole-3-acetic acid ([3H]N3IAA). Photoaffinity labelling was effectively competed for by auxins as well as by

Maize (Zea mays L.) beta-glucosidase (beta-d-glucoside glucohydrolase, EC 3.2.1.21) was extracted from the coleoptiles of 5- to 6-day-old maize seedlings with 50 millimolar sodium acetate, pH 5.0. The pH of the extract was adjusted to 4.6, and most of the contaminating proteins were cryoprecipitated

The hydrolysis of beta-D: -glucosidic bonds which is required for the liberation of many physiologically important compounds is catalyzed by the enzyme beta-glucosidase (BGLU, EC 3.2.1.21). BGLUs are implicated in several processes in plants, such as the timely response to biotic and abiotic

beta-Glucosidase (beta-D-glucoside glucohydrolase, E.C. 3.2.1.21, beta-Glu) isozyme variants were studied in a large number of inbred lines, crosses, and races of maize (Zea mays L.). The pattern of Mendelian inheritance demonstrated for beta-GLU variants indicated that they are under nuclear gene

Plants have a variety of glycosidic conjugates of hormones, defense compounds, and other molecules that are hydrolyzed by beta-glucosidases (beta-D-glucoside glucohydrolases, E.C. 3.2.1.21). Workers have reported several beta-glucosidases from maize (Zea mays L.; Poaceae), but have localized them

The treatment of healthy, undamaged plants of the Lima bean Phaseolus lunatus with solutions of a beta-glucosidase from bitter almonds (at 5 U.ml-1) through the petiole results in an enhanced emission of volatiles to the environment. The compounds are identical with those emitted in response to

Maize (Zea mays L.) beta-glucosidase was extracted from shoots of a wild-type (K55) and a "null" (H95) maize genotype. Enzyme activity assays and electrophoretic data showed that extracts from the null genotype had about 10% of the activity present in the normal genotype. Zymograms of the null

The role of beta-glucosidase during the phototropic response in maize (Zea mays) coleoptiles was investigated. Unilateral blue light illumination abruptly up-regulated the activity of beta-glucosidase in the illuminated halves, 10 min after the onset of illumination, peaking after 30 min and

Beta-glucosidases such as Zm-p60.1 (Zea mays) and Bgl4:1 (Brassica napus) have implicated roles in regulating plant development by releasing biologically active cytokinins from O-glucosides. A key determinant of substrate specificity in Zm-p60.1 is the F193-F200-W373-F461 cluster. However, despite

The maize (Zea mays) beta-glucosidase Zm-p60.1 has been implicated in regulation of plant development by the targeted release of free cytokinins from cytokinin-O-glucosides, their inactive storage forms. The crystal structure of the wild-type enzyme was solved at 2.05-A resolution, allowing

Human cytosolic beta-glucosidase (hCBG) is a xenobiotic-metabolizing enzyme that hydrolyses certain flavonoid glucosides, with specificity depending on the aglycone moiety, the type of sugar and the linkage between them. Based upon the X-ray structure of Zea mays beta-glucosidase, we generated a

Gentiobiose, a β-1,6-linked glycosyl-disaccharide, accumulates abundantly in Gentianaceae and is involved in aspects of plant development, such as fruits ripening and release of bud dormancy. However, the mechanisms regulating the amount of gentio-oligosaccharide accumulation in plants remain

Sorghum (Sorghum bicolor L. Moench) has two isozymes of the cyanogenic beta-glucosidase dhurrinase: dhurrinase-1 (Dhr1) and dhurrinase-2 (Dhr2). A nearly full-length cDNA encoding dhurrinase was isolated from 4-d-old etiolated seedlings and sequenced. The cDNA has a 1695-nucleotide-long open reading

The purification of 6-O(4-O)-indole-3-ylacetyl-beta-D-glucose (IAGlc) hydrolase from immature kernels of maize (Zea mays) was undertaken to separate this enzyme from 1-O-IAGlc hydrolase and beta-glucosidase. Partially purified 6-O(4-O)-IAGlc hydrolase was found to be the specific enzyme catalyzing
