Abstract[English]
The present invention relates to glycoside phosphorylases which are useful for the production of isomelezitose (α-D-glucopyranosyl-(1,6)-β-D-fructofuranosyl-(2,1)-α-D-glucopyranoside). More specifically, the invention relates to sucrose 6(F)-phosphate phosphorylases (EC 2.4.1.329), which catalyze, among other things, the synthesis of isomelezitose from a suitable glycoside donor and isomaltulose, where said glucosyl donor can be sucrose or α-D-glucose 1- phosphate. The present invention further relates to a method for producing isomelezitose using said sucrose 6(F)-phosphate phosphorylases.[French]
La présente invention concerne des phosphorylases glycosidiques servant à la production d'isomélézitose (α-D-glucopyranosyl-(1,6)-β-D-fructofuranosyl-(2,1)-α-D-glucopyranoside). Plus précisément, l'invention concerne les sucrose 6(F)-phosphate phosphorylases (EC 2.4.1.329), lesquelles catalysent, entre autres, la synthèse de l'isomélézitose à partir d'un donneur de glycoside approprié et d'isomaltulose, ledit donneur de glucosyle pouvant être du saccharose ou de l'α-D-glucose 1-phosphate. La présente invention concerne également un procédé de production d'isomélézitose à l'aide desdites sucrose 6(F)-phosphate phosphorylases.
