Abstract: The invention relates to a method for producing derivatives of O-?-glucosylated flavonoid, comprising at least one step of incubating a glucansucrase with a flavonoid and at least one sucrose, the flavonoid being a flavonoid which is monohydroxylated or hydroxylated in a non-vicinal manner on the B cycle. The invention also relates to novel O-?-glucosylated flavonoid derivatives, and to the use thereof.

Abstract: A method of producing 2,4-dihydroxybutyric acid (2,4-DHB) by a synthetic pathway that includes transforming malate into 4-phospho-malate using a malate kinase, then transforming 4-phospho-malate into malate-4-semialdehyde using a malate semialdehyde dehydrogenase, and then transforming malate-4-semialdehyde into 2,4-DHB using a DHB dehydrogenase.

Abstract: A method of producing 2,4-dihydroxybutyric acid (2,4-DHB) by a synthetic pathway that includes the transforming malate in 4-phospho-malate using a malate kinase, said 4-phospho-malate being transformed in malate-4-semialdehyde using a malate semialdehyde dehydrogenase and said malate-4-semialdehyde being transformed in 2,4-DHB using a DHB dehydrogenase.

Abstract: Method for preparing the disaccharide [?-D-Gldp(1?3)]-?-L-Rhap-YR wherein Y is selected from —O— and —S— and R is selected from the group consisting of: C1-C6 alkyl, C1-C6 alkenyl, aryl, allyl, —CO-alkyl (C1-C6), —CO-alkenyl (C1-C6), —CO-aryl comprising the step of using a mutant of a wild type glycoside hydrolase.

Abstract: Method for preparing the disaccharide ?-D-glucopyranosyl-(1?4)-2-N-acetyl-2-deoxy-?-D-glucopyranoside, comprising the step of using a mutant of a wild type glycoside hydrolase.

Abstract: The invention relates to structures and models of glycosyltransferases and ligand binding domains of glycosyltransferases, and complexes of the glycosyltransferases and ligand binding domains with ligands. The structural coordinates that define the structures and models enable the determination of homologues, the structures of polypeptides with unknown structure, and the identification of modulators of the glycosyltransferases. The invention also relates to structures and models of nucleotide-sugar donors and acceptors for the glycosyltransferases, and the design of modulators for the glycosyltransferases based on the properties of these structures and models.

Abstract: The invention relates to the design of inhibitors for glycosyltransferases, and in particular to computer-implemented methods for designing the inhibitors. The invention also relates to compositions and treatments using the inhibitors.
