Directed evolution of a fucosidase from a galactosidase by DNA shuffling and screening
An efficient β-fucosidase was evolved by DNA shuffling from the Escherichia coli lacZ β-galactosidase. Seven rounds of DNA shuffling and colony screening on chromogenic fucose substrates were performed, using 10,000 colonies per round. Compared with native β-galactosidase, the evolved enzyme purifie...
