donors in the syntheses of oligosaccharides. In addition, such heavy atom analogs of natural glycosides are useful tools for structure determination of their lectin receptors using X-ray crystallography. Some lectins, e.g., members of the tectonin family, only bind to carbohydrate epitopes with O-alkylated ring hydroxy groups. In this context, we report the first synthesis of an O-methylated selenoglycoside

The present invention relates to a field of genetically modified fungal cells and converting galacturonic acid to meso-galactaric acid, more precisely to a method of producing meso-galactaric acid. The invention further relates to recombinant fungal cells having a specific combination of modifications including but not limited to expression of uronate dehydrogenase enzyme, reduced D-galacturonic acid reductase activity, and furthermore reduced meso-galactaric acid catabolism, as well as uses and methods related thereto.
