Radio Frequency Identification (RFID) is a system that uses radio frequency to transmit identification wirelessly. Its functionality is much more powerful than bar code system, with which a contacting reader must be used to read the bar code. RFID, on the other hand, may read the information stored in a tag with a non-contact reader from a distance as far(More)
Cytosolic Oryza sativa glyceraldehyde-3-phosphate dehydrogenase (OsGAPDH), the enzyme involved in the ubiquitous glycolysis, catalyzes the oxidative phosphorylation of glyceraldehyde-3-phosphate to 1,3-biphosphoglycerate (BPG) using nicotinamide adenine dinucleotide (NAD) as an electron acceptor. We report crystal structures of OsGAPDH in three conditions(More)
Lectins with sugar-binding specificity are widely distributed in higher plants and various other species. The expression of rice lectin from Oryza sativa is up-regulated in the growing coleoptile when anaerobic stress persists. A rice lectin of molecular weight 15.2 kDa has been crystallized using the hanging-drop vapour-diffusion method. From the(More)
Fructosyltransferases catalyze the transfer of a fructose unit from one sucrose/fructan to another and are engaged in the production of fructooligosaccharide/fructan. The enzymes belong to the glycoside hydrolase family 32 (GH32) with a retaining catalytic mechanism. Here we describe the crystal structures of recombinant fructosyltransferase (AjFT) from(More)
Branched-chain aminotransferases (BCAT), which utilize pyridoxal 5'-phosphate (PLP) as a cofactor, reversibly catalyze the transfer of the α-amino groups of three of the most hydrophobic branched-chain amino acids (BCAA), leucine, isoleucine, and valine, to α-ketoglutarate to form the respective branched-chain α-keto acids and glutamate. The BCAT from(More)
Chitinases hydrolyze chitin, an insoluble linear polymer of N-acetyl-d-glucosamine (NAG)(n), into nutrient sources. Bacillus cereus NCTU2 chitinase (ChiNCTU2) predominantly produces chitobioses and belongs to glycoside hydrolase family 18. The crystal structure of wild-type ChiNCTU2 comprises only a catalytic domain, unlike other chitinases that are(More)
Glycosyltransferases (GTs), which are distributed widely in various organisms, including bacteria, fungi, plants and animals, play a role in synthesizing biological compounds. Glycosyltransferase-1 from Bacillus cereus (BcGT-1), which is capable of transferring glucose to small molecules such as kaempferol and quercetin, has been identified as a member of(More)
OBJECTIVES Esophageal squamous cell carcinoma (ESCC) is common in hypopharyngeal squamous cell carcinoma (HSCC) patients. This prospective study is to reveal the prevalence of simultaneous ESCC in newly diagnosed HSCC patients by unsedated transnasal esophagogastroduodenoscopy (EGD) and to analyze the clinical predictors for simultaneous esophageal lesions(More)
OBJECTIVE This study compared the characteristic parameters of ocular vestibular-evoked myogenic potential (oVEMP) test between eyes gazing up and eyes closed to evaluate the feasibility of oVEMP test with eyes closed. METHODS Twenty-three healthy adults underwent oVEMP testing with upward gaze and with eyes closed in a randomized order. For each(More)
