WebbAmylomaltases (4-α-glucanotransferases, E.C. 2.4.1.25) are enzymes which can perform a double-step catalytic process, resulting in a transglycosylation reaction. They hydrolyse glucosidic bonds of α-1,4′-d-glucans and transfer the glucan portion with the newly available anomeric carbon to the 4′-position of an α-1,4′-d-glucan acceptor. The … Webb31 mars 2007 · Alpha-glucan phosphorylase catalyzes the reversible cleavage of α-1-4-linked glucose polymers into α-D-glucose-1-phosphate. We report the recombinant production of an α-glucan/maltodextrin phosphorylase (PF1535) from a hyperthermophilic archaeon, Pyrococcus furiosus , and the first detailed biochemical characterization of …

Here, a thermophilic 4-α-glucanotransferase from Thermoproteus … WebbThe recently discovered potato tuber ( Solanum tuberosum ) -glucan, water dikinase (GWD) (formerly known as R1) catalyzes the phosphorylation of starch by a dikinase-type reaction mechanism in which the β-phosphate of ATP is transferred to either the C-6 or the C-3 position of the glucosyl residue of starch. In the present study, we found that the GWD …
Webb7 apr. 2024 · We identified four genes encoding starch synthesis enzymes, including starch synthase (glgA), 1,4-alpha-glucan branching enzyme (GBE1), glucose-1-phosphate adenylyltransferase (glgC), and UTP-glucose-1-phosphate uridylyltransferase (UGP2). For sucrose metabolism, we found eighteen genes were associated with sucrose … Webb1 maj 2012 · Introduction. Starch is the major dietary carbohydrate for humans. It consists of two glucans, amylose and amylopectin. Amylose is composed of long linear chains of D-glucose units linked by α-1,4-glycosidic linkages with few branches; while amylopectin has higher molecular weight with shorter linear glucans linked by α-1,4-linkages and is highly …
WebbStarch is a mixture of two polymers: amylose and amylopectin. Natural starches consist of about 10%–30% amylose and 70%–90% amylopectin. Amylose is a linear polysaccharide …
