AdvanceBio Sialidase A, Sampler Kit

Popis produktu: Agilent Exoglycosidases (formerly ProZyme) are glycoside hydrolase enzymes that cleave the glycosidic bonds at the terminal residues. These enzymes are useful in the study of isolated glycans, glycolipids, glycoproteins. Linkage-specific exoglycosidases may also be used for sequencing of oligosaccharides. When used in combination, exoglycosidases enable flexible analytical tools for glycan analysis.

Zdroj enzymu: Recombinant gene from Arthrobacter ureafaciens expressed in E. coli. Sialidases are also known as neuraminidases.
Enzymová aktivita: -
Specifita enzymu: 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.
Definice enzymové jednotky: One unit is defined as the amount of enzyme required to catalyze the release of 1 µmole of p-nitrophenol from p-nitrophenyl-?-D-N-acetylneuraminic acid per minute at 37° C, pH 5.5
