A new property of recombinant trehalose synthase (GTase) from Thermus thermophilus HB-8 (ATCC 27634) was found and described in this study. GTase can act on sucrose and catalyze trehalulose formation without isomaltose, isomaltulose, or isomelezitose, releasing small amounts of glucose and fructose

We have characterized the putative α-glucosidase gene (st2525) selected by total genome analysis from the acidothermophilic crenarchaeon Sulfolobus tokodaii strain 7. The ORF was cloned and expressed as a fusion protein in Escherichia coli, and recombinant ST2525 was purified by Ni-NTA affinity chr

OBJECTIVE: A combined load of carbohydrate and protein stimulates insulin secretion. However, results on postprandial glucose responses in type 2 diabetic (T2D) subjects have been inconclusive. Therefore, we investigated the effects of co-ingestion of carbohydrate and protein on glucose and insulin

… The structures of the E277A isomaltase mutant from Saccharomyces cerevisiae in complex with isomaltose or maltose were determined at resolutions of 1.80 and 1.40Å, respectively. … The root mean square deviations between the corresponding mainchain atoms of free isomaltase and the E277A-isomaltose complex structures and those of free isomaltase and the E277A-maltose complex structures were found to be 0.131Å and 0.083Å, respectively. …
