alpha-L-Fucosidase Products

Description

Recombinant R. gnavus alpha -L-Fucosidase His-tag ( alpha -L-Fuc) catalyzes the hydrolysis of terminal alpha -L-Fucose. alpha -L-Fuc is monomeric and consists of two distinct domains, an N-terminal catalytic domain comprising residues 46-366 and a C-terminal F5/8 Type C domain covering residues 385-526 (1). Residues 23-45 wrap around the C-terminal beta -sandwich domain (1). R. gnavus is an early colonizer of the human gut but persists in healthy adults (2-3). An increasing number of studies are reporting a disproportionate representation of R. gnavus in diseases, such as inflammatory bowel disease (4). To access a source of nutrients, gut bacteria encode alpha ‑L‑fucosidases that catalyze the hydrolysis of terminal alpha -L-fucosidic linkages. alpha -L-Fuc has the capacity to recognize fucosylated glycans and to hydrolyze both alpha 1‑3 (Lewis X) and alpha 1–4 (Lewis A) fucosyl linkages although the preferred substrate is sialyated Lewis X epitope (1). This fucosidase specificity can potentially be exploited for use in human disease diagnostic assays, as a tool to identify N-glycan biomarkers of disease, and for glycoprofiling biopharmaceutical glycoproteins. The activity of alpha -L-Fuc is demonstrated in an electrophoretic gel mobility shift assay using a fluorophore-labeled glycan Cy5-Fuc labeled Lewis X as the substrate (5).
