In enzymology, a 4-alpha-glucanotransferase is an enzyme that catalyzes a chemical reaction that transfers a segment of a 1,4-alpha-D-glucan to a new position in an acceptor carbohydrate, which may be glucose or a 1,4-alpha-D-glucan. This enzyme belongs to the family of ...
(EC 2.4.1.25;4-alpha-glucanotransferase) in starch metabolism has been suggested. Transgenic potato plants with reduced D-enzyme activity have been obtained. Polyphenol oxidase, peroxidase, and catalase enzymes involved in the oxidation of phenols bring about browning of the freshly cut surface of ...
4-Alpha-Glucanotransferase was purified from cells of Thermococcus litoralis, a hyperthermophilic archaeon. The molecular mass of the enzyme was estimated to be approximately 87 kDa by gel filtration. The optimal temperature for its activity was 90 degrees C. The enzyme catalyzed the transglycosylation...

4-alpha-glucanotransferaseGelation of starch is a process during short-term retrogradation. However, long-term retrogradation always leads to the quality deterioration of starch-based food. In this work, a new type of modified tapioca starch (MTS) gel with maintained short-term gelation strength ...

6-alpha-GlucanotransferaseMalto-oligosaccharidesImmune-modulatory functionsA wide number of Lactic Acid Bacteria (LAB) species produce alpha-glucans with their ability to synthesize glucansucrases (GS) which use sucrose as substrate for the glucan production. Recently another group of enzymes in LAB ...

Using 3-ketobutylidene-#betA#-2-CHLORO-4-NITROPHENYL-MALTOPENTAOSIDE (3 KBG 5 CNP) as a donor and glucose as an acceptor, we shoed that the disproportionation reaction of 4-#alpha#-glucanotransferase involves a Ping-Pong Bi Bi mechanism. Based on this reaction mechanism, we trapped the ...
