α1-2 Fucosidase is a highly specific exoglycosidase that catalyzes the hydrolysis of linear α1-2 linked fucose residues from oligosaccharides

  • Recombinant enzyme with no detectable endoglycosidase or other exoglycosidase contaminating activities
  • Glycerol-free for optimal performance in HPLC and mass spectrometry analysis
  • ≥95% purity, as determined by SDS-PAGE and intact ESI-MS
  • Optimal activity and stability for up to 12 months
Substrate Specificity: substrate specificity
α1-2 Fucosidase is a highly specific exoglycosidase that catalyzes the hydrolysis of linear α1-2 linked L-fucopyranosyl residues from oligosaccharides (1). In this case, a linear substrate is defined as having no branching on the adjacent residue.

All reactions contained 1X Glycobuffer 1. All reactions contain 1X rHSA in a total volume of 10 μl, and all reactions were incubated at 37°C. All reactions contained 20 units of α1-2 fucosidase. Reaction (C) also contained 20 units of α-N-Acetylgalactosaminidase (#P0734). In Reaction (C), the branched α 1-2 fucose is removed in the presence of both enzymes, but not by α1-2 Fucosidase alone.

Product Source

Properties & Usage

Unit Definition

One unit is defined as the amount of enzyme required to cleave > 95% of the α-L-fucose from 1 nmol of Fucα1-2Galβ1-4Glc-7-amino-4-methyl-coumarin (AMC), in 1 hour at 37°C in a total reaction volume of 10 µl.

Notes
  • Supplement w/100μ/ml rHSA. Incubate at 37°C
  • p-nitrophenyl-α-L-Fucopyranoside is NOT a substrate for this enzyme.
  • Repeated freeze/thaw cycles may reduce activity. Recommended storage temperature has changed to 4°C.
  • Optimal incubation times and enzyme concentrations must be determined empirically for a particular substrate.
