β-Glucosidases (EC 3.2.1.21) split β-glucosidic linkages at the non-reducing end of glucosides and oligosaccharides to release β-D-glucose. One of the important functions of plant β-glucosidase is deglucosylation of inactive glucosides of phytohormones to regulate levels of active hormones.
An ethyl acetate extract of Oryza sativa (rice) hulls yielded seven compounds: hentriacontane, 1-tetratriacontanol, beta-sitosterol, momilactone A, momilactone B, tricin (a flavonoid), and beta-sitosterol-3-O-beta-D-glucoside. The structures of these compounds were elucidated with 500 MHz nuclear
GH5BG, the cDNA for a stress-induced GH5 (glycosyl hydrolase family 5) beta-glucosidase, was cloned from rice (Oryza sativa L.) seedlings. The GH5BG cDNA encodes a 510-amino-acid precursor protein that comprises 19 amino acids of prepeptide and 491 amino acids of mature protein. The protein was
Rice (Oryza sativa) BGlu1 beta-glucosidase was expressed in Escherichia coli with N-terminal thioredoxin and hexahistidine tags and purified by immobilized metal-affinity chromatography (IMAC). After removal of the N-terminal tags, cation-exchange and S-200 gel-filtration chromatography yielded a 50
OBJECTIVE
Endoplasmic reticulum (ER) stress has been implicated as a cause of various neurodegenerative diseases. We evaluated the protective effects of purple rice (Oryza sativa L.) bran extract (PRE) and its constituents, namely cyanidin, peonidin, and a newly isolated compound
Nojirimycin bisulfite andp-nitrophenyl-1-thio-ß-D-glucoside, potent inhibitors of ß-glucanase, suppressed cortical dissociation and callus growth in rice roots (Oryza sativa L. cv. Sasanishiki) in the presence of 2,4-D, with resultant suppression of the emergence of callus clumps from the interior
The bglu1 cDNA for a beta-glucosidase cloned from rice (Oryza sativa L.) seedlings was expressed as a soluble and active protein in Escherichia coli and designated BGlu1. This enzyme hydrolysed beta-1,4-linked oligosaccharides with increasing catalytic efficiency (kcat/Km) values as the DP (degree
Glycoside hydrolase family 1 (GH1) beta-glucosidases play roles in many processes in plants, such as chemical defense, alkaloid metabolism, hydrolysis of cell wall-derived oligosaccharides, phytohormone regulation, and lignification. However, the functions of most of the 34 GH1 gene products in rice
