Abstract:
A mixture of human milk oligosaccharides that consists essentially of 6'-SL, LNnT and LSTc, made by treating 6'-SL and LNnT in the presence of an α2,6-transsialidase.
Abstract:
The invention provides engineered enzymes of transsialidase and/or sialyl transferase activity that have increased regioselectivity and/or increased thermostability.
Abstract:
Mutated fucosidases are provided demonstrating improved properties in terms of thermal stability and transfucosidase synthetic performance compared with a wild type transfucosidase isolated from Bifidobacterium longumsubsp. infantis.
Abstract:
The invention relates to methods for making an α-amino-aldehyde, preferably a 2-amino-2-deoxy sugar derivative, from an α-hydroxy-aldehyde, preferably an aldose. Intermediary 1-amino-1-deoxy-ketose derivatives, and their use as synthetic intermediates, are also described.
Abstract:
A method for modifying galactosyl disaccharides in order to enhance their bifidogenic effect, comprising reacting at least one glycosyl donor with a precursor galactosyl disaccharide or a mixture of precursor galactosyl disaccharides using enzyme catalysis, compounds obtainable by said method and the use of such compounds in consumable products.
Abstract:
The invention relates to providing isolactosamine (Galβ1-3GlcN 2 , formula 1) and salts thereof in the form of either anomer or mixture thereof, as well as hydrates or solvates of the free base and salts thereof. Isolactosamine derivatives of formula 2, the synthesis of isolactosamine by hydrogenolysis of said derivatives and the use of isolactosamine in the synthesis of lacto- N -biose containing oligosaccharides, through the steps of masking the amino group of isolactosamine with a suitable protecting group, protecting the OH-groups, activating the anomeric position to obtain a lacto- N -biosyl donor and coupling the lacto- N- biosyl donor to a desired sugar moiety, are also disclosed.
Abstract:
