unnaturally occurring beta-glycosidase variant, recombinant polynucleotide, vector, host cell, methods for producing at least one unnaturally occurring beta-glucosidase variant for conversion of a glycosyl group-acceptor substrate to a beta-glycosylated product and for transglycosylation of a substrate, and, composition.

摘要

The present invention provides modified β-glycosidase (bgl) enzymes, polypeptides having bgl activity, and polynucleotides encoding these enzymes, as well as host vectors and cells comprising these polynucleotides and polypeptides. The present invention also provides compositions comprising the enzymes, and methods of using the modified bgl enzymes to prepare β-glycosidic bond products.
