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-α-糖基转移酶(4-alpha-glucanotransferase, 4αGT)是一种多功能的糖基转移酶,在淀粉工业上具有广泛的应用,如淀粉改性及海藻糖,麦芽寡糖,大环糊精,糖原等淀粉深加工产品的制备.其中,以淀粉为原料制备海藻糖的工业生产过程中,借助4αGT的歧化活性,能够减少葡萄糖,麦芽糖等副产物的含量,从而提升海藻糖产量.在该...
4-α-Glucanotransferase (GTase) enzymes (EC 2.4.1.25) modulate the size of α-glucans by cleaving and reforming α-1,4 glycosidic bonds in α-glucans, an essential process in starch and glycogen metabolism in plants and microorganisms. The glycoside hydrolase family 57 enzyme (GTase57) studied...
