Enzyme Source	Recombinant gene from Arthrobacter ureafaciens expressed in E. coli. Sialidases are also known as neuraminidases.
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	One unit is defined as the amount of enzyme required to catalyze the release of 1 µmole of p-nitrophenol from p-nitrophenyl-α-D-N-acetylneuraminic acid per minute at 37° C, pH 5.5
pH Optimum	6
