Exoglycosidases

Part Number:
GK80045

AdvanceBio Sialidase A, 51 kDa (formerly ProZyme). A lower mol wt version of GK80040 sialidase A for challenging digestions. Releases α(2-3)-, α(2-6)-, α(2-8), and α(2-9)-linked N-acetylneuraminic acid from oligosaccharides and glycoproteins. Also capable of releasing N-glycolylneuraminic acid. Lower mol wt sialidases may help desialylate glycans if steric hindrance is an issue. If you think a lower mol wt sialidase will help desialylate your glycans, you can also try our 88, 66 and 51 kDa Sialidase A Sampler Kit (GK40043).  Sialidases are also known as neuraminidases.'

Volume
  • 500 µL
Enzyme Specificity
  • The enzyme releases a(2,3)-, a(2,6)-, a(2,8)-, and a(2,9)-linked N-acetylneuraminic acid from complex carbohydrates. The initial rate of hydrolysis of a(2,6) linkages is reported to be approximately twice that of a(2,3)-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. Sialidase A is capable of releasing N-glycolylneuraminic acid (Neu5Gc, NGNA) in addition to N-acetylneuraminic acid (Neu5Ac, NANA) [1], although similarly to other sialidases [2] the activity is lower toward Neu5Gc than Neu5Ac. The enzyme can also be used to remove sialic acid from gangliosides [3], glycosphingolipids (ceramide and oligosaccharide) with sialic acid. May be used for exoglycosidase sequencing with Sialidase S (GK80021), which is specific for a(2,3)-linked sialic acids. Sialidases are also known as neuraminidase.
Enzyme Unit Definition
