Product Introduction

α1-2,4,6 Fucosidase O is a broad specificity exoglycosidase that catalyzes the hydrolysis of terminal α1-2, α1-4 and α1-6 linked fucose residues from oligosaccharides. α1-2,4,6 Fucosidase O cleaves α1-6 fucose residues more efficiently than other linkages.

  • 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 24 months

Properties & Usage

Unit Definition

One unit is defined as the amount of enzyme required to cleave > 95% of the fucose from 1 nmol of GlcNAc(Fucα1-6)β1-4GlcNAc-AMC in 1 hour at 37°C in a total reaction volume of 10 µl.

Reaction Conditions

1X GlycoBuffer 1
Incubate at 37°C

1X GlycoBuffer 1
5 mM CaCl2
50 mM sodium acetate
(pH 5.5 @ 25°C)

Storage Buffer

20 mM Tris-HCl
50 mM NaCl
1 mM EDTA
pH 7.5 @ 20°C

Heat Inactivation

65°C for 10 minutes

Molecular Weight

Apparent: 49 kDa

Unit Assay Conditions

Two fold dilutions of α1-2,4,6 Fucosidase O are incubated with 1 nmol AMC-labelled substrate and 1X GlycoBuffer 1 in a 10 µl reaction. The reaction mix is incubated at 37°C for 1 hour. Separation of reaction products are visualized via thin layer chromatography (1).

Product Notes

  1. The enzymatic unit definition is calculated using a 37°C reaction temperature, to accommodate for simultaneous glycosidase digestions and N-glycan sequencing protocols. However, the optimal reaction temperature for α1-2,4,6 Fucosidase O is 50°C. A 37°C reaction temperature results in ~35% lower activity.
  2. In order to achieve complete removal of core α1-6 fucose residues from glycans with instant labels, it may be necessary to use longer incubation times (18 hours).
  3. α1-2,4,6 Fucosidase O is only active on an intact antibody if it is trimmed to the trimannosyl core.
  4. Reactions may be scaled-up linearly to accommodate larger reaction volumes.

Tech Tips

The optimal pH range is 4.5 – 5.5.

 

If using the enzyme alone (without other glycosidases), recommended incubation temperature is 50°C.

 

Longer incubation times (4 hours to overnight) may be needed for digestion of complex, oligosaccharides with multiple branches.
