Fucose is released from fucose-containing polymers by an enzyme found in lysosomes called α-fucosidase. CD BioGlyco has advanced Enzymatic Release methods to provide clients with high-quality fucose release services.
Fucose is a deoxyhexose sugar with the chemical formula C6H12O5, which is present in a variety of glycoproteins and glycolipids produced by insects, plant cells, and mammals. In mammals, fucose-containing glycans play important roles in transfusion responses, host-microbe interactions, selectin-mediated leukocyte-endothelial adhesion, and many ontogenic events. Fucosylation is the transfer of fucose residues from guanosine diphosphate (GDP)-fucose donor to an acceptor molecule and is part of the ABO blood group and Lewis antigen systems. According to the different fucose addition sites, fucosylation is divided into α1-2-, α1-3/4-, α1-6-, and O-fucosylation. In humans, fucosylation is carried out by a group of 13 enzymes, each showing a specific activity.
The potential applications of fucose are becoming increasingly apparent in the fields of medicine and dietary supplements. In immunoglobulins, fucosylation of antibodies has been established to reduce binding to Fc receptors on natural killer cells, thereby reducing antibody-dependent cell-mediated cytotoxicity (ADCC). Therefore, fucosylated monoclonal antibodies have been designed to recruit the immune system to cancer cells and have been made in cell lines lacking the core fucosylase (FUT8), thereby enhancing cell killing in vivo.
Enzymes are useful for the structural analysis of glycans and polysaccharides and for establishing structure-activity relationships in biological systems. Due to the biological importance of fucose, it is highly necessary to develop a systematic strategy to release fucose from protein. At CD BioGlyco, we have developed a Glycan Release platform to provide clients with efficient and accurate fucose release services. Fucosidase is a unique tool for hydrolyzing fucose on proteins. Under the action of fucosidase, we efficiently release α1-2, α1-3, and α1-4 linked fucose present on N-glycosylated proteins, O-glycosylated proteins, or free oligosaccharides.
