Abstract

Here, we report the biochemical characterization of a novel α-l-fucosidase with broad substrate specificity (FpFucA) isolated from the mycelial fungus Fusarium proliferatum LE1. Highly purified α-l-fucosidase was obtained from several chromatographic steps after growth in the presence of l-fucose. The purified α-l-fucosidase appeared to be a monomeric protein of 67 ± 1 kDa that was able to hydrolyze the synthetic substrate p-nitrophenyl α-l-fucopyranoside (pNPFuc), with K
