GKE-5003 PNGase F

 

Glyko® PNGase F (Chryseobacterium [Flavobacterium] meningosepticum)

Specificity:

PNGase F releases intact N-linked oligosaccharides from glycoproteins and glycopeptides. The enzyme will not cleave oligosaccharides from a single asparagine residue and cleavage does not occur if there is core α1-3 linked fucose as commonly encountered in plant glycoproteins Phosphate, sulfate and sialic acid groups attached to the oligosaccharide do not affect cleavage.

Applications:

 

  • release of intact N-linked glycans from glycopeptides and glycoproteins
  • structure-function studies of N-glycosylated glycoproteins
  • preparation of deglycosylated proteins for molecular weight estimation or crystallography studies

GK80040 Sialidase A™/NANase III

 

Glyko® Sialidase A™/NANase III (recombinant gene from Arthrobacter ureafaciens, expressed in E. coli)

Specificity:

The enzyme releases α2-3, α2-6, α2-8, and α2-9 linked N-acetylneuraminic acid from complex carbohydrates. The initial rate of hydrolysis of α2-6 linkages is reported to be approximately twice that of α2-3 linked sialic acid however, in practice, this kinetic selectivity is of little consequence during extended incubations. Effective digestion of glycolipid substrates is facilitated by addition of a detergent, such as sodium taurodeoxycholate to the incubation.

GKX-5017 Sialidase N™

 

Glyko® Sialidase N™ (Newcastle disease virus, Hitchner B1 Strain)

Specificity:

This sialidase is highly α2-3 linkage specific, cleaving non-reducing terminal sialic (N-acetyl neuraminic, NeuNAc) acid α2-3 linked to galactose or N-acetylgalactosamine. It also cleaves α2-8 linked sialic acid, commonly encountered in polysialic acid. Cleavage of sialic acid α2-6 linked to galactose, N-acetyl-galactosamine or N-acetylglucosamine does not occur. There is some specificity towards the N- and O- acylation patterns of the sialic acids.

Applications:

  • This sialidase is the most highly selective commercially available enzyme for removal of α2-3 linked sialic acid and as such has been extensively used for the removal of sialic acid and, in conjunction with broader specificity sialidases for the analysis of sialylation patterns of both lipid and protein associated glycoconjugates in isolated and whole cell systems.

GKX-5018 Sialidase T™

 

Glyko® Sialidase T™ (recombinant gene from Salmonella typhimurium, expressed in E. coli)

Specificity:

This sialidase has a 260-fold kinetic preference for α2-3 linked over α2-6 linked terminal sialic acid. This bias is not unusual for bacterial sialidases, but the magnitude is somewhat greater than others. This preference puts the enzyme from S. typhimurium between that from Newcastle disease virus (Cat No: X-5017) which is effectively α2-3 specific and from C. perfringens (Cat No: X-5020) which show approximately 3-fold preference for this linkage.

Despite the preference for α2-3 linked sialic acid the S. typhimurium enzyme is also active against α2-6 linked sialic acid and when the enzyme is used in excess, these linkages can be completely degraded.

Applications:

  • This sialidase's activity at physiological pH and ionic strengths make it an ideal candidate for the modification of intact cells as well as isolated glycoconjugates. The ability to digest gangliosides efficiently, even in the absence of detergent confirms this.

GKX-5021 Sialidase I

 

Glyko® Sialidase I (recombinant gene from Clostridium perfringens, expressed in E. coli)

Specificity:

This enzyme has a broad specificity, active against isolated oligosaccharides, gangliosides, glycoproteins and mucins. The enzyme favors cleavage of α2,3 linked N-acetylneuraminic acid by a factor of about 2.5-3.0, but in practice distinction between these linkages in practice does not occur. N-glycolyl derivatives of sialic acid are also cleaved efficiently.

O-acetylation can affect specificity. 9-O-acetyl neuraminic acid is cleaved, but, in contrast to Newcastle disease virus sialidase (Cat. No. X-5017), the 4-O-acetyl analogue is not cleaved. The enzyme will cleave gangliosides; this activity is enhanced by the presence of detergent, (although the enzyme from A.ureafaciens Cat.No. 80040) is more efficient in this application.

Applications:

The enzyme is an established tool for glycoconjugate research. It has been used in the structural and functional analysis of the role of sialic acids on all types of glycoconjugate, ranging from whole organs to isolated molecules; in all aspects of sialic acid biology, from viral and neurotransmitter receptor function to cancer diagnosis.

The enzyme specifically cleaves non-reducing terminal α1-3 or α1-4 fucose residues.

After digestion with 0.2 mU/ml enzyme at a substrate concentration of 40 µM in 50 mM sodium acetate pH 5.0, 2 nmol of LNFPII is completely de-fucosylated. 3'fucosyllactose (2 nmol) was 65% de-fucosylated by 5 mU of a1-3/4 fucosidase during a 24hr incubation. However, under equivalent conditions, no fucose was release from 3' sialo-3-fucosyllactose. Higher enzyme concentrations (>2 mU/ml) are found to be required for the removal of α1-3 or α1-4 fucose residues from complex N-glycans. Complete hydrolysis of Fuc α1-3 GlcNAc from the outer arms of a di α1-3 fucosylated, di α1-2 fucosylated bi-antennary N-glycan isolated from Human parotid gland was obtained at a final substrate concentration of 1 mM and a final enzyme concentration of 3 mU/ml.

Applications:

 

  • The enzyme can be used in the analysis of fucosylated O- and N-linked glycans during exoglycosidase sequencing It has also been used in the analysis and modification of blood group oligosaccharides since it is active towards the Lex antigen.
