FoFCO1 was purified from culture filtrates of Fusarium oxysporum strain 0685 grown on L-fucose and its encoding gene identified in the sequenced genome of strain 4287. FoFCO1 was active on p-nitrophenyl-α-fucoside (pNP-Fuc), but did not defucosylate a nonasaccharide (XXFG) fragment of pea xyloglucan. A putative α-fucosidase gene (FgFCO1) from Fusarium graminearum was expressed in Pichia pastoris. FgFCO1 was ~1,800 times less active on pNP-Fuc than FoFCO1, but was able to defucosylate the XXFG nonasaccharide. Although FgFCO1 and FoFCO1 both belong to Glycosyl Hydrolase family 29, they share <25 % overall amino acid identity. Alignment of all available fungal orthologs of FoFCO1 and FgFCO1 indicated that these two proteins belong to two subfamilies of fungal GH29 α-fucosidases. Fungal orthologs of subfamily 1 (to which FoFCO1 belongs) are taxonomically more widely distributed than subfamily 2 (FgFCO1), but neither was universally present in the sequenced fungal genomes. Trichoderma reesei and most species of Aspergillus lack genes for either GH29 subfamily.
