Enzymic synthesis of a new type of fucose-containing glycolipid with fucosyltransferase of rat ascites hepatoma cell, AH 7974F.

An alpha-fucosyltransferase activity has been demonstrated in rat ascites hepatoma AH 7974F cells catalyzing the transfer of L-fucose to asialo-GM1 prepared from bovine brain GM1 ganglioside to form a fucolipid in the presence of Triton X-100. The radioactive fucolipid was shown to be Fuc-(alpha1 leads to 2)-Gal-(beta1 leads to 3)-GalNAc-(beta1 leads to 4)-Gal-(beta1 leads to 4)-Glc-ceramide from the following results. The radioactive product coincided with authentic blood group H-active fucolipid from AH 7974F cell on thin-layer chromatography. The product formed a precipitation line not only with Ulex europeus lectin but also with eel anti-H serum on agarose gel plates. The terminal 14C-labeled fucose was released by Bacillus fulminans alpha(1 leads to 2)fucosidase as well as Charonia lampas alpha-fucosidase. The optimum pH value for the incorporation of L-fucose into asialo-GM1 was 5.8 in cacodylate/HCl buffer. The fucosyltransferase was highly specific for asialo-GM1.[1]
