Mammalian alpha-fucosidase (EC 3.2.1.51) is a lysosomal enzyme that catalyzes the removal of fucose residues from glycosphingolipids and its absence in humans results in a rare metabolic disorder called fucosidosis. Among the invertebrates in the molluscs (Unio) two forms of the enzyme have been reported, a 68 kDa non-glycosylated form and a 56 kDa glycosylated form. The glycosylated form has been purified from the seminal fluid of Unio [Biochem. Biophys. Res. Commun. 234 (1997) 54]. In the present study, the 56 kDa glycosylated form has been purified to homogeneity from the whole body tissue of Unio using a series of chromatographic steps. The purified enzyme migrated as a single protein species in 10% SDS-PAGE. Antibodies to the purified enzyme were raised in a rabbit in order to study its biochemical and immunological properties. The purified enzyme is a glycoprotein that exhibits strong binding to Con A-Sepharose gel and can be deglycosylated by PNGase F enzyme suggesting it to be N-glycosylated. The enzyme has been shown to specifically interact with the mannose 6-phosphate receptor protein (MPR 300) purified from goat and Unio. This specific interaction is discussed in view of its possible in vivo binding partners.
