Glucan 1,4-a-glucosidase)Also found in: Dictionary, Thesaurus, Encyclopedia. amylase [am´ĭ-lās] an enzyme that catalyzes the hydrolysis of starch into simpler compounds. The α-amylases occur in animals and include pancreatic and salivary amylase; the β-amylases occur in higher ...
GLUCOAMYLASEThe food enzyme glucoamylase (4‐α‐D‐glucan glucohydrolase; EC 3.2.1.3) is produced with the genetically modified Trichoderma reesei strain DP‐Nzh38 by Danisco US Inc. The genetic modifications do not give rise to safety concerns. The food enzyme is free...

3057α-Glucosidase rapidly hydrolyzes these glycosides. Maltooligosaccharide derivatives incorporating genipin [methyl (1R,2R,6S)-2-hydroxy-9-(hydroxymethyl)-3-oxabicyclo[4.3.0]nona-4,8-diene-5-carboxylate, 2], used for analysis of alpha amylases, have been prepared from geniposide (3) and a ...

Only two of the newly identified enzymes, a putative α-glucosidase (AgdB) and an α-amylase (AmyC), were predicted to play a role in starch degradation. The expression of the majority of the genes identified was not induced by maltose as carbon source, and not dependent on the presence ...
Glycogen debranching enzyme (4-alpha-glucanotransferase amylo-1,6-glucosidase, EC 2.4.1.25 + 3.2.1.33) was purified 140-fold from dogfish muscle in a rapid, high-yield procedure that takes advantage of a strong binding of the enzyme to g... JU Becker,TJ Long,EH Fischer - 《Biochemistry》...
Briefly, β-glucan was hydrolyzed by lichenase into oligosaccharides, which were converted into glucose by β-glucosidase. The amount of glucose released was measured by UV absorbance with glucose oxidase/peroxidase. The β-glucan content was calculated based on the amount of released glucose. ...
overcomes these limitations. In this assay, highly purified endo-1,3(4)-β-glucanase (lichenase) and β-glucosidase are employed. The glucan is depolymerized by lichenase to oligosaccharides, these oligosaccharides are quantitatively hydrolyzed by β-glucosidase to glucose, and this is specifically ...
alpha-Amylases (1,4-alpha-D-glucan glucanhydrolase, EC 3.2.1.1) areendoenzymeswidely distributed in nature (Tiwari, Srivastava and Singh, 2015), which randomly hydrolyze alpha-1,4glycosidic bondswithin the starch molecule, acting onamyloseandamylopectin(Guzmán-Maldonado, Paredes-López and Biliader...
