The present disclosure relates to an a-fucosidase having a-(1,2), a-(1,3), a-(1,4), and a-(1,6) fucosidase activity. The present disclosure also relates to the compositions comprising the a-fucosidase, and the methods of producing and using the a-fucosidase in cleaving a-(1,2), a-(1,3), a-(1,4), and/or a-(1,6)-linked fucoses in the glycoconjugates. Accordingly, the present invention provides the compositions and methods for the improved enzymatic hydrolysis of fucose in vitro. In particular, the present invention is useful for the efficient cleavage of core fucose in native glycoproteins without denaturation or functional deterioration of glycoproteins. The compositions and methods of the invention can facilitate the Fc glycoengineering of Fc fusion proteins or antibodies, such as therapeutic antibodies. |
