Endo D is an endoglycosidase that cleaves within the chitobiose core of paucimannose N-linked glycans, with or without extensions in the antennae, from glycoproteins and glycopeptides.

  • Tagged with a chitin binding domain (CBD) for easy removal
  • Recombinant enzyme with no detectable exooglycosidase or other endoglycosidase 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


 
Endo D, also known as Endoglycosidase D, is a recombinant glycosidase, which cleaves within the chitobiose core of paucimannose N-linked glycans, with or without extensions in the antennae. Endo D is tagged with a chitin binding domain (CBD) for easy removal from a reaction, and is supplied glycerol-free for optimal performance in HPLC and MS- intensive methods.

Product Source
A truncated Endo D gene cloned from Streptococcus pneumoniae and expressed in E. coli as a fusion to chitin binding domain

Properties & Usage

Unit Definition

One unit is defined as the amount of enzyme required to remove > 95% of the carbohydrate from 10 μg of glycosidase-trimmed (trimannosyl core) Fetuin in 1 hour at 37°C in a total reaction volume of 10 μl.

Reaction Conditions

1X GlycoBuffer 2
Incubate at 37°C

1X GlycoBuffer 2
50 mM Sodium Phosphate
(pH 7.5 @ 25°C)

Storage Buffer

20 mM Tris-HCl
50 mM NaCl
1 mM EDTA
pH 7.5 @ 25°C

Heat Inactivation

65°C for 10 minutes

Molecular Weight

Apparent: 140000 daltons

Unit Assay Conditions

10 μg of glycosidase-trimmed (trimannosyl core) Fetuin are denatured with 1X DTT at 95°C for 3 minutes. After the addition of 1X GlycoBuffer 2, two-fold dilutions of Endo D are added and the reaction mix is incubated for 1 hour at 37°C. Separation of reaction products is visualized by SDS-PAGE.

Notes
  • To deglycosylate a native glycoprotein, longerincubation time, as well as more enzyme, maybe required.
  • Endo D is not recommended foruse with Glycoprotein Denaturing Buffercontaining both SDS and DTT, as Endo D is inhibited by SDS and, unlike otherendoglycosidases, NP-40 does not counteractthe SDS inhibition.
  • Removal of Endo D from thedeglycosylation reaction can be scaled uplinearly with larger amounts of chitin magneticbeads.
  • Chitin Magnetic Beads Binding Capacity is0.4 μg/μl of CBD-tagged protein.
  • 50 μl of chitin slurry are sufficient to remove 1-5 μl of Endo D (50-250 units)
