-glucosidase (Rutinosidase) from <i>Aspergillus niger</i>
: Characterization and Synthetic Potential of a Novel Diglycosidase
We report the first heterologous production of a fungal rutinosidase (6‐O‐α‐L‐rhamnopyranosyl‐β‐D‐glucopyranosidase) in Pichia pastoris. The recombinant rutinosidase was purified from the culture medium to apparent homogeneity and biochemically characterized. The enzyme reacts with rutin and cleaves the glycosidic linkage between the disaccharide rutinose and the aglycone. Furthermore, it exhibits
